Store-bought spicy mustard, take a back seat. If you want real heat and chili pepper flavor, you’ll want to make it at home. This spicy jalapeño mustard recipe spices things up just right.

It’s a Dijon mustard, and the tang from the white wine complements perfectly the spiciness and bright flavor of the jalapeño. Control your heat by increasing or decreasing the amount of jalapeños used, or you can opt for jumping up the pepper scale and using serrano peppers instead.
