Make your own prepared yellow mustard. It is so simple, and it is much healthier to eat!
Achieving a perfectly smooth texture is paramount; vigorously whisk dry ingredients with liquids before heating, and continue stirring often while simmering to prevent lumps and scorching. The mustard will thicken considerably upon cooling, so avoid over-reducing it. For enhanced flavor, consider blooming the mustard powder in a tiny bit of hot vinegar before combining with other liquids to fully release its pungency. Experiment with adding a touch of sweetness like honey or maple syrup, or a dash of finely minced shallot or garlic (sautéed first) for a more complex profile. For longer shelf life and improved emulsion, ensure thorough cooking to activate the flour's thickening properties, and store in a sterilized, airtight container. Always taste and adjust salt after cooling, as flavors meld and concentrate.
