Wondering what to do with that head of cauliflower in the frig? Tired of plain ol' steamed cauliflower? Ho hum. Well, with little effort and just a bit of aplomb, you can transform that humble veggie into an exotic meal-opener. A delightful, gourmet cold soup that will leave your guests asking, what IS this--it's delicious? (Don't tell them it's only cauliflower!) The secret is to use only the freshest spices. Freshly toasted and ground spices are the best. But if you do use a ready-made curry powder, be sure to select one that is fresh and does not contain salt.
