Shisho is a term that often leads to lively debates among cooks, herb enthusiasts and food historians. In many kitchens, it is used interchangeably with Shiso – the bright, aromatic leaf popular in East Asian cooking – yet the spellings and pronunciations vary across cultures and languages. This long-form guide aims to demystify Shisho, exploring its origins, its varieties, and the many ways it can elevate modern British and international cuisine. Whether you already cook with Shiso leaves or you’re simply curious about a herb that brings a unique sweetness and peppery note to dishes, this article offers practical advice, tested techniques, and plenty of inspiration.
Throughout this piece you will encounter the term Shisho in its various forms, along with the closely related Shiso. Where relevant, you’ll also see discussion of how these leaves are used in different culinary traditions. Our aim is to give readers a clear understanding of Shisho and its kin, while providing the kind of practical guidance that makes a well-used herb a staple in everyday cooking.
Shisho and Shiso: Clarifying the Terms
Shisho is frequently encountered in modern cookery blogs, markets and recipe books as a variant spelling of the herb known as Shiso. In botanical terms, Shiso refers to the plant species Perilla frutescens, with culinary varieties that include green Shiso and red or purple Shiso. The name Shisho can be seen in certain languages or transliterations, and in some contexts it is used to capture a particular phonetic flavour. In this guide, Shisho and Shiso are discussed together, with care taken to note when a distinction matters for flavour or colour. In recipes, you might see Shisho leaves called for fresh or powdered, or Shiso oil used to impart a clean, citrusy aroma.
The Varieties: Green Shiso, Red Shiso, and Beyond
Shisho exists in several varieties that influence taste, colour and texture. Understanding these differences helps home cooks select the right leaf for the dish, and explains why some recipes call for one version over another.
Green Shiso (Aojiso)
Green Shisho, or Aojiso, is the most commonly used leaf in everyday cooking. Its flavour is bright and refreshing, with hints of mint, anise and basil. It adds a gentle pepperiness and a striking aroma that complements cucumber, tofu, seafood and rice. The leaves are typically serrated, slightly soft to the touch, and vibrant green. In Western kitchens, Green Shiso is a sure-fire way to introduce a distinctly Asian note without overpowering the dish.
Red or Purple Shiso (Gomae Shiso or Akashiso)
Red Shisho, sometimes described as purple Shiso, brings a deeper colour and a more pronounced anise-like sweetness. Its flavour carries a subtle black-currant nuance, making it an excellent foil for fatty fish, citrus, sesame and miso-based dressings. Red Shiso can lend a dramatic hue to salads and plates, but its stronger flavour means it is often used judiciously—think garnishes, pickling, or finishing oils rather than base ingredients.
Other Varieties and Related Plants
Within culinary contexts, you may encounter other Perilla cultivars and related herbs used in fusion dishes. These can share aroma compounds with Shisho and offer alternative colour profiles or heat tolerances. For the practical home kitchen, sourcing Green Shiso or Red Shiso from reputable markets or online suppliers will cover the vast majority of recipes that call for Shisho.
Shisho in Culinary Traditions: Techniques, Flavours and Pairings
In Japanese cuisine, Shisho is used both as a fresh leaf and as a flavouring agent. It appears in sushi garnishes, salads, soups and pickles, and can be pressed into oils or blended into dressings. In Korean and some Southeast Asian kitchens, similar herbs are used to brighten dishes and balance rich flavours. British cooks have adopted Shisho for its brightness, allowing it to stand up to bold ingredients such as smoked fish, citrus, and creamy sauces. Below are practical techniques and pairing ideas to integrate Shisho into your repertoire.
Raw Use: Fresh Leaves as Garnish and Accent
Fresh Shisho leaves offer an immediate burst of aroma and a pleasant peppery note. Tear or finely slice leaves just before serving to preserve their essential oils. Add Shisho to sashimi platters, salads, or as a garnish for gravlax and grilled fish. A few delicate ribbons can transform a plate, lifting a modest dish into something distinctly fragrant and fresh.
Shisho in Salads and Dressings
Shisho pairs beautifully with cucumber, radish, lettuce, and avocado. Create a simple Shisho vinaigrette by whisking together rice vinegar, sesame oil, a touch of soy sauce and finely chopped Shisho. Drizzle over a green salad, or toss through a light noodle or soba dish for a British-meets-Asian flavour profile that remains restrained and balanced.
Pickled Shisho: Quick Pickling and Preserves
Shisho can be pickled to preserve its flavour and colour. A straightforward method is to thinly slice the leaves, scatter with a pinch of salt and sugar, and allow to marinate in a light rice vinegar solution for 20 to 30 minutes. Pickled Shisho is excellent alongside grilled vegetables, rice bowls or as a bright finishing touch on meat dishes.
Shisho Oil and Marinades
Infuse light oil with Shisho leaves to produce a delicate, aromatic oil suitable for drizzling over fish, grilled chicken or vegetables. A simple method is to warm a neutral oil gently, add Shisho leaves, then strain after a short infusion. The resulting oil carries a citrusy, herbaceous scent that brightens the dish without overpowering it. Use Shisho oil sparingly; a few drops can transform a sauce or finish a plate.
Temperature and Cooking: When Not to Overcook Shisho
Shisho leaves can lose their vibrant colour and aroma when subjected to long cooking. For this reason, many chefs prefer to add Shisho at the end of cooking, or use it as a finishing herb rather than as a primary component. If you’re experimenting with hot dishes, consider gently warming the leaves or adding them as a last-minute touch to preserve aroma and colour.
Growing, Harvesting and Storing Shisho at Home
For readers who want fresh Shisho from their own garden or kitchen windowsill, the herb is a rewarding addition. It thrives in temperate climates, including many parts of the United Kingdom, provided it receives adequate sun and well-draining soil. Here are practical steps for growing, harvesting and storing Shisho to maintain flavour and vitality.
Growing Shisho: Light, Soil and Water
Shisho prefers a sunny or partially shaded spot with rich, well-drained soil. Amend heavy soil with compost to improve drainage and moisture retention. Regular watering is important, particularly in dry spells, but avoid waterlogging. If you’re growing in pots, choose a size that allows the plant to spread and ensure good drainage holes.
Propagation: From Seed or Cuttings
Shisho can be grown from seeds or by taking softwood cuttings. For seeds, sow in early spring indoors or directly outdoors after the last frost. Transplant seedlings when they are sturdy enough to handle. Cuttings should be taken from healthy plants in late spring or early summer, then placed in a potting mix with a rooting hormone to encourage rapid rooting.
Harvesting: When and How to Pick
Harvest leaves as needed, beginning with the outermost older leaves. Regular trimming encourages a bushier plant and prolongs productivity. Pick leaves in the morning after the dew has dried to preserve essential oils and aroma. Avoid removing more than a third of the plant at a time to maintain growth and health.
Storage: Fresh, Dried and Frozen Options
To keep Shisho fresh for a few days, wrap the stems in a damp paper towel and place the bunch in a loosely closed plastic bag in the fridge. For longer storage, dry leaves in a warm, dry place away from direct sun or freeze chopped leaves in ice cube trays with a little water or oil. Dried Shisho retains aroma fairly well if stored in an airtight container away from light.
Nutritional Profile and Health Benefits of Shisho
Shisho is more than a flavour-enhancing leaf; it carries beneficial compounds that contribute to a balanced diet. While traditional medicine systems may vary in their emphases, modern nutrition recognises several pillars of Shisho’s appeal.
Key Nutrients
Shisho leaves provide vitamins A and C, along with minerals such as calcium and iron in modest amounts. While not a calorie-dense food, the herb contributes to daily intake with a focus on micronutrients and phytonutrients. The aroma compounds in Shisho, including perillaldehyde, lend characteristic fragrance and may support digestive comfort when used as part of a broader, varied diet.
Antioxidant and Anti-Inflammatory Qualities
Perilla-derived oils and essential oils in Shisho have been studied for their antioxidant potential and anti-inflammatory properties. Incorporating Shisho into meals may contribute to a healthful, diverse diet, particularly when paired with vegetables, grains and lean proteins.
Digestive Wellbeing and Appetite
Aromatic herbs such as Shisho can support flavour-induced appetite and may aid digestion by stimulating saliva and stomach secretions. While Shisho is not a substitute for medical advice, using it mindfully as part of a balanced plate can support enjoyable, varied meals.
Substitutes and Where to Buy Shisho
If you can’t access fresh Shisho, you can turn to substitutes that offer a similar brightness or peppery note. Fresh basil combined with a pinch of mint or cilantro can approximate Shisho’s refreshing lift in certain dishes. For pickles or oils, a small amount of lemon zest and coriander may help mimic the herb’s citrusy aroma. When possible, buy fresh Shisho from reputable grocers, Asian markets or online herb specialists to ensure quality, aroma and intensity align with your recipe.
Recipes to Try: Simple Shisho-Based Dishes for Everyday Cooking
Below are a few approachable ideas that showcase Shisho, whether you are working with Shisho leaves, Shiso oil or a perfume-rich dressing. These dishes illustrate how Shisho can enhance rather than overwhelm, making it a versatile ally in the kitchen.
Shiso-Infused Vinegar Dressing
Combine a mild oil (such as grapeseed) with rice vinegar and a handful of torn Shisho leaves. Let the mixture steep briefly, then strain. Use the dressing on cucumber salads, seafood platters or as a finishing drizzle for baked white fish. The result is crisp, aromatic and light, perfect for summer menus.
Cucumber and Shiso Salad
Thinly slice cucumber and toss with sliced red onion, a splash of rice vinegar, sesame oil and chopped Green Shisho. Add sesame seeds for texture. This salad is refreshing, with a gentle heat and herbaceous zing that lifts simple vegetables into a refined course.
Grilled Fish with Shisho and Lemon
Season fish with salt and pepper, then grill briefly. Finish with a drizzle of Shisho oil, a squeeze of lemon, and a few torn Shisho leaves. The citrus notes highlight the fish while the herb adds complexity and brightness to the plate.
What is Shisho? Is it the same as Shiso?
In many culinary contexts, Shisho is used as a variant spelling of Shiso. The herb commonly known as Shiso is Perilla frutescens. If a recipe asks for Shisho and you have Shiso available, you can use it as a direct substitute; the flavour and aroma remain closely related.
Can Shisho leaves be eaten raw?
Yes. Fresh Shisho leaves can be eaten raw and are often used as a garnish or ingredient in salads and sashimi platters. Rinse gently, pat dry, and add to dishes at the last moment to preserve aroma and colour.
Is Shisho edible in large quantities?
Like many aromatic herbs, Shisho is best used in moderation. A little goes a long way, and it is especially valuable as a finishing herb. Excessive use can overwhelm other flavours and may cause an overpowering taste.
Where can I buy Shisho or Shiso?
Specialist Asian supermarkets, farmers’ markets and online herb suppliers typically stock fresh Shisho or Shiso. Look for leaves with bright colour, strong aroma and no signs of wilting or yellowing. If you purchase dried Shisho, ensure the product is well sealed and stored away from light to preserve its essential oils.
Shisho in Modern British Cooking: A Conclusion
Shisho, in its many forms, offers a vivid way to brighten dishes, whether you’re preparing a simple salad, a delicate fish course or a bold, contemporary plate. With Green Shiso and Red Shisho providing complementary flavours and colours, the herb invites experimentation without demanding a steep learning curve. From growing your own plant to creating infusions and finishing oils, Shisho is accessible to home cooks and professional chefs alike in the United Kingdom.

Shisho is a gift to be used thoughtfully, and with care, it will reward your cooking with layers of colour, scent and flavour that linger pleasantly on the palate.
Whether you call it Shisho or Shiso, the herb remains an exemplary example of how nature’s small greens can transform a plate.
