I love Crab Rangoon, even remember the first place I had it.
I was catering in the late 70's when the crab rangoon craze started again. The recipe I used was : 3 cups cream cheese, 1 cup minced crab (usually canned), 2 tbsp Lea and Perrins, 2 tbsp lemon juice, salt and white pepper. Used a melon baller for a scoop, put it in the middle of a wonton, wet the edges and form into a pyramid. Deep Fry, serve with soy sauce and sweet and sour.
