Ground Yellow Mustard Seeds is a finely milled powder made from yellow mustard seeds, Brassica alba. It is a warm, aromatic kitchen staple used in rubs, marinades, curries, stews, mustard pastes, chutneys, relishes, pickles, salad dressings and sauces. Mustard seed powder also works as a mild functional emulsifier in dressings and sauces when whisked with oil and vinegar. In home body-care routines, it is traditionally used in warming bath soaks with Epsom salts and sparingly in rinse-off scrubs or soaps.
♡ Why we love it: Yellow mustard seed powder brings bold, nutty warmth to savoury recipes and blends smoothly into sauces without grit. It is a versatile pantry ingredient that also has a place in traditional warming bath preparations.

I was disappointed that the mustard powder was ground whole mustard seed and had a coarse texture and was quite oily. I was expecting a dry fine mustard powder that I could use for making a smooth mustard. The photo is representative of the product. I just did not pay attention
