2tablespoonrapeseed oil (or other mild flavored oil)

Instructions
Combine the mustard powder, water and vinegar in a saucepan and let sit for 5 minutes.
Mix in the starch and spices with the sugar. Add in the mustard mixture.
Boil 5 minutes while constantly stirring. (so no clumps form from the starch)
Pour in one larger glass jar or 2 smaller ones. Store in the fridge.
Notes
The consistency will thicken in the fridge. The mustard stores for weeks in the fridge if you take it always from the jar with a clean spoon. To get some less heat in the mustard do not let the powder sit with the liquid, but boil it immediately after stirring and add less vinegar.
