I've always come back from France with food snobbery ... which has to pass quickly when I'm confronted by everyday reality!! At a perfectly ordinary restaurant in Paris (we could not afford haute cuisine!) I had a fish terrine in three colours, very delicate, with a pale orangey seafood sauce which was sublime. The French do not waste food, and it was clear that the basis of the sauce was stock/broth made from shrimp or crab or lobster shells. This was my take on it, back home. I shelled the prawns to get my stock base, and lightly fried the shrimps/prawns and served it over fettucine. It was delicious. As you can see, the ingredients are quite simple, healthy and low-fat. The recipe is about the sauce, really, and MY PHOTO IS OF THE TERRINE we had in Paris: NOTE THE SAUCE.
