Made Mustard
Ingredients
Directions
Make the mustard
In a bowl, combine the mustard and salad oil, stirring with a wooden spoon until smooth.
Gradually add vinegar until the mixture forms a stiff paste.
Mix in salt, pepper, and sugar thoroughly.
Continue to add vinegar little by little until the consistency resembles cake batter.
Beat the mixture for a short time, then transfer it to mustard bottles.
Rest and store
Pour a little oil on top and let it sit for 24 hours before using.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- English mustard
- Provides the main flavour and pungency that defines the condiment.
- Vinegar
- Thins the paste and adds acidity that sharpens the mustard's heat.
- Salad oil
- Blends with the mustard to give a smooth texture and mellow richness.
The step that matters
Adding the vinegar gradually. Adding vinegar too fast can leave the paste lumpy or too thin to control. Adding it little by little lets you reach a stiff paste first, then a batter-like consistency, so the texture stays smooth.
Swap the white pepper
How well each one fits the dish's main ingredients (mustard, sugar, vinegar):
- Tarragonfits better
- Capersfits better
- Allspicefits better
- White pepperthe original
Fit is the average pairing score against mustard, sugar, vinegar. Candidates are from the same food group and used in at least 100 recipes.
