Yellow mustard seed, sometimes called white mustard, is much more mild than brown, with a smoother heat and pungency. It is much easier to use because of this, and is the far more common ingredient in cooking throughout the Americas and Asia. Mustard seed can be toasted or fried while building complex curries, sauces, and stews, to give the mustard a nutty warmth. Mustard seed is frequently used in pickling, and also in steaming or frying vegetables, which it complements very well.
