Turmeric has a flavor, albeit mild. It is often refered to as "the poor man's saffron", and has a similar flavor. AS mentioned above, it does impart a rich, yellow color. Use it anywhere that a dry, almost dusty flavor might help the dish, such as egg salad sandwich filling, potato salad, deviled eggs, scrambled eggs, as an addition to a Bechemel Sauce, dusted lightly on fish for broiling or baking. You can use it in mashed potatoes, Potatoes Anna, in macaroni dishes, curries and sauces, chicken gravy, etc.
It is also great for soups, daahl, in lentle dishes, mixed in with flaur for seasoned flour mixes (think fried chicken).
I think its flavor would go great with lamb.
These are just a few of the ways that turmeric can be used. You will be able to find ohters as you explore this underated spice.
