Recipe: Jalapeno Pepper Sauce (using tomatoes, onions, sugar and vinegar)

Hi Rebecca, I'm excited! I found this recipe on an old CD I have of recipes that I have from assorted community cookbooks. Unfortunately there is no credit given in the recipes, but this recipe fits your description and I'm hoping its at least very similar to the one you're looking for. I imagine your Mother and Grandmother would be very happy to know you want to recreate this fond food memory. Please let us know if you try it and if you make any changes to it.
Happy Cooking!
