Mustard, prepared, yellow

Prepared yellow mustard is made from ground mustard seed mixed with vinegar, water, and turmeric for its bright yellow color, giving it a tangy, mildly spicy flavor that's less sharp than Dijon or brown mustard. It's the classic condiment for hot dogs, hamburgers, and pretzels, and it's also whisked into salad dressings, deviled egg filling, and glazes for ham or roasted vegetables, where its acidity cuts through richer, fattier foods. A spoonful stirred into a vinaigrette helps emulsify the oil and vinegar together, which is a common trick for a smoother, less separating dressing. It's also brushed onto pretzels before baking and mixed into barbecue sauces and marinades for its tang.

An unopened bottle keeps in the pantry, but once opened it should go in the refrigerator, where the acidity keeps it stable for months even if the color darkens slightly over time. At only 60 calories per tsp-scale serving with 4 grams of fiber and 14% DV fiber per 100 g, it's an easy way to add a bit of fiber to a sandwich or dressing without adding many calories, and its 1,100 mg of sodium per 100 g means a little goes a long way as a flavor booster rather than a base ingredient.
