Peel cucumbers and cut in half, scooping out the seeds. Rub with salt and vinegar. Fill with the meat mixed with seasonings and put the halves together fastening with a string or baking needles. Brown the bacon and finely chopped onion in the butter in a deep skillet or casserole dish. Put in the cucumbers; fill the skillet or dish with hot water (not too much or they will give up much fluids) and cook until they are soft. Take the cucumbers out and season and thicken the gravy with cornstarch. Cooking time is about 30 min.
