My husband came home from America and proudly Presented me with about 4 cups worth of dried cilantro he bought from pensey's spices. I do love pensey's, but I don't see how coming from pensey's can save this stuff from it's existential crisis. What do I do with 4 cups of dried cilantro?
Cilantro (or as the rest of the world calls it, coriander) is one of the most ridiculously applicable cooking herbs I have had the privilege of using.
That said, you are correct - when dried, it's application becomes far more limited (to a far greater extent than most other herbs and spices).
I have successfully used dried coriander in english stews, curries, pies, ice-cream, fried/breakfast egg seasoning, salads and coffee.
I have not successfully used it in stir-fries, any asian cooking, thai curries, or anything complicated or french, where fresh coriander does seem to work.
Take this with a grain of salt, but I think it has something to do with the way coriander breaks down in slow-cooked or oil-heavy dishes, so fast stuff or with coconut milk etc doesn't work so well with the dried herb.
In Caribbean cooking, you can use it in rice and beans dishes. Namely rice with red or black beans. Add while stewing the beans. If you're using canned cooked beans, add it just as you're starting the burner, so that the flavor has a chance to come out.
