FAQs

Q1: What is the most profitable spice for UK restaurants?

Turmeric is considered the most profitable because it’s used in almost every curry base, marinade, Indian dish, and Indo-Chinese gravy. It has very high shelf life, low cost per kg, high colour strength, and extremely low wastage. Restaurants often report a 20–30% reduction in spice cost when switching to bulk turmeric packs.

Q2: Is it worth buying spices in 1kg or 5kg quantities?

Yes — for high-usage spices like cumin, coriander, chilli, turmeric, and paprika, bulk sizes offer significant savings. Most restaurants use them daily, meaning the risk of expiry is low. 5kg packs deliver the best cost-per-gram ROI.

Q3: Which spices help with colour consistency in curries?

Kashmiri chilli powder, paprika, and turmeric are the top three for natural colour consistency. They give restaurants predictable shade intensity, which customers notice immediately.

Q4: What is the best storage method for bulk spices?

Keep spices in airtight containers, away from heat, sunlight, and moisture. Use FIFO rotation and label bags with open dates to prevent loss of potency.

Q5: Are curry powders or whole spices more profitable?

Curry powders are more profitable for restaurants focused on speed. Whole spices are better for premium dining, but require more time and labour. Many kitchens use both based on the dish.

Q6: How often should restaurants refresh their spice inventory?

High-turnover restaurants should rotate every 4–6 weeks. Medium-speed kitchens can refresh every 6–10 weeks. The key is monitoring aroma strength and colour intensity.
