The best curry powder in the UK (2026 verdict)
Britain loves a curry. Friday night curry, Sunday curry leftovers, the weeknight 30-minute chicken curry that holds the kitchen together. The single biggest difference between a curry that tastes like takeaway and one that tastes like home cooking is the curry powder. Get the blend right and the dish almost cooks itself. Get it wrong and even premium chicken won't save you.
We tested a shelf of UK curry powders side-by-side over a week. This is the verdict, the winners, the losers, and how to use each. Spoiler: Costack Mild Curry Powder ranked first overall on balance, depth, and weeknight performance.
What "curry powder" actually is
Curry powder isn't a single spice. It's a pre-mixed blend that British cooks adopted from Indian regional masalas. A proper UK curry powder is built on:
- Turmeric - the yellow colour, earthy depth
- Coriander seed - the warm citrus backbone
- Cumin seed - the smoky base note
- Fenugreek - the maple-savoury sweetness
- Ginger - the brightness
- Mustard seed - the slight kick
- Black pepper - the warming finish
- Cinnamon, allspice, cardamom in trace amounts for complexity
Cheap UK curry powders skip 4-5 of these and lean on turmeric + cumin alone. Premium blends use all 8-12 ingredients at proper ratios. Costack Mild Curry Powder is a 12-spice blend. That's why it tastes layered rather than flat.
How we tested
Four cooks. Three recipes each. We cooked the same dishes using each curry powder at the recommended ratio. The three recipes:
- Quick weeknight chicken curry (25 minutes)
- Slow-cooked beef curry (3 hours)
- Vegetable dhal (45 minutes)
Scored on aroma at jar, balance, depth in finished dish, salt level, and whether the curry felt cohesive or fragmented.
The verdict, by type of blend
Costack Mild Curry Powder - £2.99
The standout performer. A 12-spice blend that delivers proper depth in 25-minute weeknight curries and holds beautifully through 3-hour slow cooks. The fenugreek and coriander balance gives it a sweetness that thinner blends never reach. Vegan and gluten-free.
Standout test result: the slow-cooked beef curry. After 3 hours, Costack still had aroma and balance, where every thinner blend had flattened by hour 2. Shop Costack Mild Curry Powder.
Mainstream supermarket curry powders
Solid, traditional British curry profiles. Strong turmeric and cumin lead. Fine for a quick chicken curry or dhal, but most faded through a long slow cook. The reliable default if you are grabbing a jar mid-shop.
Budget Madras blends
Spicier than "mild" suggests. Heavy on chilli and cumin, lighter on the aromatic spices like fenugreek and cardamom. Punchy but one-dimensional. Best value if heat is all you are after.
Premium independent blends
A mixed bag. Some are well balanced; the priciest blend in our test was mild to the point of feeling under-spiced. Good ingredients, but the ratios can feel cautious for the money.
The 4 essential UK curry recipes
1. 25-minute weeknight chicken curry
Heat 2 tbsp oil. Fry 1 chopped onion 5 minutes. Add 3 minced garlic cloves and 1 tbsp grated ginger. Add 1.5 tbsp Costack Mild Curry Powder. Fry 1 minute. Add 1 chopped tomato and 400ml chicken stock. Add 600g diced chicken thighs. Simmer 15 minutes. Stir in 100ml double cream. Season. Serve with basmati rice.
2. Slow-cooked beef curry (3 hours)
Brown 1kg diced beef. Add 2 chopped onions, 4 garlic cloves, 2 tbsp Costack Curry Powder, 1 tbsp Costack Ground Ginger, 1 cinnamon stick, 3 cardamom pods. Fry 2 minutes. Add 2 tbsp tomato paste, 500ml beef stock, 1 tin coconut milk. Simmer covered 2.5-3 hours until fork-tender. Serve with rice and naan.
3. Vegetable dhal (45 minutes)
Rinse 250g red lentils. Heat 2 tbsp oil. Fry 1 chopped onion, 3 garlic cloves, 1 chopped tomato. Add 1.5 tbsp Costack Curry Powder + half tsp Costack Hot Smoky Chilli Powder for heat. Add lentils and 800ml water. Simmer 25 minutes until lentils break down. Finish with a tarka of mustard seeds and curry leaves in ghee.
4. Curry chicken thighs (1-pan dinner)
Pat 8 bone-in thighs dry. Rub with 1.5 tbsp Costack Curry Powder + 1 tbsp Costack Chicken & Turkey Seasoning. Roast at 200C for 35 minutes on a tray with chopped onion and potato wedges underneath.
How to use curry powder properly
1. Bloom the spices first
Curry powder needs heat and oil to release its full flavour. Fry it in oil for 30-60 seconds before adding wet ingredients. This is non-negotiable. Cold curry powder added to a finished dish tastes raw and bitter.
2. Layer with whole spices for restaurant depth
Curry powder is the base. Add whole spices on top for proper restaurant flavour: a cinnamon stick, 3-4 cardamom pods, 4-5 cloves, a bay leaf. These bloom slowly in the cooking liquid and add complexity that pre-ground powder can't.
3. Use the right ratio
1 tbsp curry powder per 500g protein. 1.5 tbsp per litre of curry sauce. More is not better - over-curried dishes taste muddy and harsh.
4. Finish with fresh herbs
Curry powder needs the freshness of coriander, mint, or lemon at the end to lift the dish. Without a fresh finish, the curry tastes one-note.
Curry powder vs garam masala vs masala paste
Three different products that British home cooks often confuse:
- Curry powder - pre-mixed ground spice blend including turmeric. Used as a base seasoning at the start of cooking.
- Garam masala - pre-mixed ground spice blend WITHOUT turmeric. Heavier on cardamom, cinnamon, cloves. Added at the end for aroma.
- Masala paste - wet paste of spices + oil + tomato. Already cooked. Skip the blooming step.
For proper home curry: use curry powder at the start, finish with a sprinkle of garam masala.
FAQs about curry powder
Is curry powder the same as Indian curry?
No. Indian regional cuisines use individual spice blends (masalas) tuned to the dish - Madras masala, Punjabi masala, Goan masala. Curry powder is the British generalist version. Both work. Different traditions.
How spicy is Costack Mild Curry Powder?
Mild. Warmth from black pepper, mustard, and ginger but no chilli heat. For heat, add Costack Hot Smoky Chilli Powder separately so you control the level.
Is curry powder vegan and gluten-free?
Costack Mild Curry Powder is vegan and gluten-free. Other brands vary - always check the label.
How long does opened curry powder last?
12 months for peak aroma. Store in a cool dry place. Costack curry powder comes in a re-sealable sachet to preserve freshness.
Can I use curry powder in non-curry dishes?
Yes. Try it in roast cauliflower, soups, rice pilafs, scrambled eggs, lamb stews, fish marinades, and even chicken wing rubs. The turmeric-coriander base works anywhere you want warmth.
