Things You'll Need
1 tbsp. yellow mustard
Dry mustard is made from crushed mustard seeds, and yellow mustard is made from adding wine or vinegar to the dry mustard. If you do not have dry mustard, you can substitute it with yellow mustard it in recipes. However, you'll have to adjust the liquid ingredients to avoid ruining the taste and texture of the recipe.
Determine how much powdered mustard the recipe needs, so you can make a calculation.
Use 1 tbsp. of yellow mustard for every 1 tsp. of dry mustard. If the recipe calls for 1/2 tsp. of dry mustard, then you would use 1/2 tbsp. of yellow mustard.
Measure the yellow mustard carefully so that you use the appropriate amount. Use a measuring spoon for best results.
Decrease one of the liquids in the recipes by 1 tsp. Since you are adding liquid to the recipe with the prepared yellow mustard, you will need to take out 1 tsp. to help balance the liquid proportion.
