We don't call hot dogs frankfurters any more, but I like the alliteration. :) Great appetizer for parties. The longer they simmer, the better they get.
Mix:
1 C. Grape Jelly (My favorite is Smucker's.)
1/2 c. French's Yellow Mustard
Heat in crockpot or fondue pot.
Add:
1 lb. Frankfurters cut into bite-size pieces.
Let simmer at least 1/2 hour.
These are simple, but a favorite around my house. If you like the sauce even sweeter, you can use honey mustard. I cut the hot dogs on the diagonal, but to tell you the truth, I don't think anyone notices! They're too busy eating them.
