Can dry mustard be substituted for mustard seed when canning pickles? How much is used? Yes, dry mustard can safely be used as a substitute for mustard seed. However, it may make the brine cloudier than mustard seed and may alter the flavor. 1 teaspoon mustard seeds = 1 teaspoons dry mustard. This substitution is most likely for use in foods and in making mustard vs. being used to flavor a brine.

Mustard powder is very strong since its not mixed with other ingredients so you'll need less of it than you would with the condiment.
