This recipe, from an internet site, is screaming with flavor! I love fennel, and if you haven't tried it, do yourself a favor. Try it, and you will buy it again. Shrimp, teamed up with fennel, lemon juice, crushed red pepper flakes, and tarragon, will make your family and guests so happy. Ever been confused about the numbers associated shrimp? Not anymore! The numbers indicate how many shrimps there are in a pound, i.e. 21-30 shrimps in a pound.
