Our recommendation is to to buy whole whenever possible. Powdered mustard seeds are almost always made using old season crop, and powdering also reduces their flavour dramatically. Both yellow and black mustard seeds have their own advantages Yellow Mustard Seeds are most commonly used in western cooking, whereas Black Mustard Seeds are most popular in Indian cooking. We’ve found that mustard seeds originating from their ancient home in India taste the strongest, and display a much more wholesome flavour than those from other origins. If you’re not sure, please refer to our quality and grade standards here for yellow and here for black mustard when buying good quality seeds.
