My favorite use for leftover ham, if I had some, is an easy ham salad. I never really have leftover ham as I’m the only one in my house who eats ham. Therefore I often buy a small piece of ham with the intent of using half simply sliced and the other half for a mini batch of ham salad. I cut the ham into chunks & place them in the bowl of a food processor. I had a few cornichons (French for tiny sour gherkins) and pulse until close to the texture I like. Add mayo to taste, pulse to combine, then scrap out of processor bowl. Then I discipline my myself to not eat the whole batch with a spoon before getting it into the refrigerator.
The homemade ham salad I remember from childhood would have been made with my Gram’s bread & butter pickles. I think the ham was probably ground with one of those meat grinders that you clamped to your counter or table top. Some things change a little over xx years but my desire for ham salad in springtime does not.
