Was going to say scallops, because I have them a couple dozen times a year.
But I really have to declare my favorite to be Atlantic lobster.
Fresh, flown to the West Coast alive. I’ll eat it boiled. Grilled. Boiled and then made into a lobster roll the next day. Finely chopped in an omelet.
One time on a cold rainy April day in Paris, at a neighborhood cafe, I had the most incredible lobster bisque, oh man, it was orgasmic.
In Bar Harbor Maine, I had lobster tail, stuffed with scallops, clams, cod, potatoes, and shrimp, roasted. One of the best meals I have ever had.
