One of my mother-in-law's friends brought this delicious dip to a party and I had to have the recipe. Please only use full fat ingredients in this and real crabmeat. If you are lucky enough to have some fresh cooked crab meat, then you may certainly use that in place of canned-just don't use the "fake crab" as a substitute as it just won't taste the same. The size of the can is the same as a regular tuna fish can-I will update the exact size next time I make this. Note:The leftover dip is also great as a sandwich spread on a lightly toasted bagel with lettuce & tomato.
