Colman's-style fierce yellow mustard — yellow + brown seed ground fine, mixed with cold water 10 min before serving.
1814 Stoke Holy Cross watermill near Norwich, Jeremiah Colman ground the first batch of his double-superfine. The patented sieving process separated husk from flour for a finer powder than any rival. Royal warrant from Queen Victoria 1866; the bull's-head tin design dates to 1855 and is unchanged.
Colman is said to have made his fortune from what people leave on the plate; over 90% of household tubs go stale unused. Norwich's Colman's Mustard Shop & Museum closed in 2018 after Unilever sold the brand. The Carrow Road plant shut in 2019; production moved to Burton-on-Trent and Germany.
Mixed paste is luminous yellow, the colour of a school-bus. Hits the sinuses before the tongue — wasabi-style horseradish heat that fades inside two minutes, leaving a clean mustard-seed finish. Smear thin on roast beef, ham, pork pies, Welsh rarebit. Never pile it on.
The bite is enzymatic: myrosinase in the seed reacts with glucosinolates only when water hits the dry powder, releasing allyl isothiocyanate. Hot water or vinegar deactivates the enzyme — that's why you mix with cold tap water and wait 10 minutes. Brown seed (Brassica juncea) carries the heat, yellow seed (Sinapis alba) the body.
Variations
Colman's powder (mix yourself) vs Colman's prepared (jar, with vinegar and turmeric, milder); Tewkesbury mustard (16th century, blended with horseradish, mentioned in Henry IV, Part 2); Taylors of Newport Pagnell still mills traditional whole-seed.

Ingredients
Serves 4How it's made
5 steps · 7 min active + 10 min waiting
- 13 min
Grind 50 g yellow mustard seed + 25 g brown mustard seed in a spice grinder to fine powder.
- 21 min
Sift through fine mesh into a bowl.
- 32 min
Whisk in 2 tbsp cold water + 1 tsp salt + a pinch of turmeric until smooth paste.
Watch outMix with cold water only — warm water kills the enzyme and you lose the sharp heat, leaving flat bitter paste.
- 410 min
Let stand uncovered 10 min for full heat to develop.
Watch outLeave it uncovered and untouched — the burn builds as it sits; taste at 10 minutes and it should sting the back of the nose.
- 51 min
Stir in 1 tsp white wine vinegar to stabilize; serve fresh.
Watch outStir the vinegar in once the heat has peaked — it locks the sharpness where you want it; add it too early and the mustard stays mild.
