Mix squash, onion together in bowl.
Add egg, sugar, salt and pepper
and enough flour to hold together
(it should resemble pancake batter).
Melt equal amounts of butter and olive oil
(I start with 2 tbs. of each)
Drop by spoonfuls in skillet (should look like pancakes).

NOTE: If you do a double/triple batch, more oil/butter will be needed in pan.
