What Is Thai 7 Spice? What's in It and How to Use It

Thai 7 Spice is one of the most popular ready-made blends in UK supermarkets and spice cupboards – built to bring Thai-style warmth and aromatics to a dish without reaching for seven or eight separate jars. The name tells you the headline ingredient count, but not much about what's actually in the jar, and that varies more than you'd expect.

What's usually in it

Most versions lean on the same core aromatics: ginger, garlic, chilli, coriander and star anise, often with lemon or lime peel and a warming note from cinnamon or cardamom. Beyond that, blends diverge quite a bit from brand to brand.

Our own blend (No. 20) is ginger, garlic, chilli, coriander, lemon peel, onion, cumin, black pepper, mustard, celery salt, cinnamon, oregano, paprika and star anise.

What it tastes like

Fragrant and warm rather than fiery – ginger and garlic up front, a citrusy lift from the lemon peel, star anise and cinnamon underneath, and a gentle chilli warmth rather than real heat. It's built to be balanced, not punchy.

Why it's worth checking the label

Supermarket jars are built to a different brief than a blend made in small batches. Check the ingredients on one of the big-name versions and you'll find things like sugar, sunflower oil and plain “flavourings” sitting in a dry spice mix. “Flavourings” in particular doesn't tell you much; it's a legal catch-all that can cover a wide range of things without naming any of them. None of it needs to be dangerous to be worth noticing – it's just not what you'd put in if you were measuring out the actual spices yourself. A hand-blended version, mixed in small batches from the spices themselves rather than things added to imitate or stretch them, gets you a fresher, more distinct flavour with a shorter, plainer ingredients list.

How to use it

• Stir-fries: add to hot oil at the start to release the aromatics, then build the stir-fry around it
• Curry base: stir into coconut milk for a fast, Thai-style curry
• Marinades: mix with oil and coat chicken, fish or tofu before cooking
• Dry rub: mix with a little salt and use on chicken before roasting or grilling
• Finishing touch: a squeeze of lime and fresh coriander at the end lifts it further

A little goes a long way – a teaspoon or two is usually enough for a meal for four.

What to look for when you buy it

If you'd rather skip checking labels, our Thai 7 Spice blend is built from ginger, garlic, chilli and the rest of the list above – nothing added just to extend shelf life.

Frequently asked questions

Is Thai 7 Spice very hot?
Not especially – it's built for warmth and fragrance rather than heat. The chilli is there for a gentle kick, not to dominate.

What's the difference between Thai 7 Spice and Thai curry powder?
They overlap, but curry powder usually leans more on turmeric and a curry-forward flavour, where Thai 7 Spice is built around ginger, garlic, citrus and aniseed notes for a lighter, more aromatic result.

Can I use it in something other than Thai food?
Yes – it works well on roasted vegetables, grilled fish, or stirred into a quick noodle dish, not just classic Thai dishes.

Is Thai 7 Spice vegan?
Generally yes, since it's just a spice mix – but always check the specific brand's label for anything added.
