Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mustard flour
- Provides the main mustard flavour, which develops when it meets water.
- Wheat flour
- Adds body and thickens the paste so it holds its shape.
- Cayenne pepper
- Adds heat that sharpens the mustard's flavour.
The step that matters
Add the dissolved salt water gradually to the dry ingredients.. Adding the liquid slowly lets you stop once a stiff paste forms. Too much water at once makes the mixture runny and hard to correct. Mustard's pungency develops when the ground seed is hydrated, so the paste's moisture level also shapes the final sharpness.
Swap the mustard
How well each one fits the dish's main ingredients (pepper, flour, wheat):
- Spinachfits better
- Capsicumfits better
- Arrowrootfits better
- Mustardthe original
Fit is the average pairing score against pepper, flour, wheat. Candidates are from the same food group and used in at least 100 recipes.
