I grew up on the stuff in a can, and have to say I adore the greasy, salty, gritty taste!
However, after tasting this, I do have to say that home made Deviled Ham is easy to make yourself, and about a thousand times better that the stuff in the can. And as an added bonus, you can add whatever flavors you wish!
1/2 cup mayonnaise (you may need more)
1/4 cup prepared mustard
1/2 cup chopped onion
2 tablespoons hot sauce (recommended: Tabasco)
1 tablespoon Worcestershire sauce
2 teaspoons paprika (I used 1)
1 teaspoon mustard powder
