How to Make Yellow Mustard, and where to source it
Mustard's heat is a chemical reaction, not a spice level — it fires when ground seed meets cold water, peaks in about fifteen minutes, then fades. Vinegar stops that reaction dead. Add it early for something mild and stable, late for something that will take the roof of your mouth off.

The Method
Wake the powderWhisk the mustard powder with the cold water and let it sit ten minutes. It will smell sharp and sinus-clearing — that's the reaction you want, and it's at full strength right now.
Stop it where you like itTaste carefully. Add the vinegar now for a mild, stable mustard; wait another five minutes for something considerably hotter. Once the vinegar is in, the heat is locked.
Add the restTurmeric, salt, sugar. Whisk smooth and simmer gently for five minutes to take the raw floury edge off.
Rest before you judge itFresh mustard tastes harsh and bitter. Refrigerate at least twenty-four hours — it mellows dramatically and only then tastes like mustard. Keeps for months.
Make it yoursWhole seeds soaked overnight and stirred through give you a grainy mustard. Raw honey makes honey mustard properly. Beer instead of water is the classic Bavarian move. Horseradish, harissa, or hot honey each take it somewhere useful.
