I used to make a tea with a couple of teaspoons of water and a few threads of saffron for Challa bread and my lemon pound cake. It gave beautiful color and fragrance to both. I have recently found that a few threads really add flavor and color to the sauce in which I prepare Turbot. I use a little olive oil and various herbs and seasonings under the fish, more seasonings, salt and some splashes of Frank's red hot cayenne pepper sauce on top and a few tablespoons of white wine, with the saffron threads, in the pan to bubble and provide steam in the covered skillet. If the sauce needs reducing, I slightly set the cover ajar the last couple of minutes of cooking. I serve it with a really garlicy heavily herbed marinara sauce on top of each fillet.
