Try this one:
6 squash, chopped
2 large bell peppers, chopped
4 medium onions, chopped
2 1/2 c apple cider vinegar
1/4 c canning salt
3 c sugar
2 tsp celery seed (I also use 1 tsp. mustard seed)
Recipe calls for all veggies to be chopped, or you can use a food process, depending on your texture preference.
Put chopped veggies in a large bowl and add salt. Cover with ice and let set for one hour. Drain Well. Add the rest of the ingredients. Bring to a boil. Boil for 10 minutes. Put in hot jars. Makes 5 pints.
I would recommend giving the jars a hot bath to ensure a good seal after canning. We made these the other night and they turned out great. We even substituted half the squash with zucchini and we like it even better. Hope you guys enjoy. Let me know if you have any questions.
