If you add corn, you would need to follow the guidelines for canning mixed vegetables. It will be soft, as you know.Is it that you don't like the celery ? If so, just leave it out if you want. I have never heard of antipasto with corn before. Just curious. Mixed Vegetables 6 cups sliced carrots 6 cups cut, whole kernel sweet corn 6 cups cut green beans 6 cups shelled lima beans 4 cups whole or crushed tomatoes 4 cups diced zucchini Optional mix  You may change the suggested proportions or substitute other favorite vegetables except leafy greens, dried beans, cream-style corn, winter squash and sweet potatoes. Yield: 7 quarts Procedure: Except for zucchini, wash and prepare vegetables as described for carrots, corn, lima beans, snap beans or italian beans and tomatoes. Wash, trim, and slice or cube zucchini; combine all vegetables in a large pot or kettle, and add enough water to cover pieces. Add 1 teaspoon salt per quart to the jar, if desired. Boil 5 minutes and fill jars with hot pieces and liquid, leaving 1-inch headspace. Adjust lids and process pints,75 min. quarts 90 min. in a pressure canner. Use 11 lb dial gauge canner, 10 lb. weighted, unless you live at higher altitudes.

Gee, I may have to get a new Ball Book, mine's from the 70's. Sounds like there's a lot of good stuff in the new one. Yeah, Dave, I know what you're going to say. I learned to can from my mother-in-law who raised ten kids on stuff she either open kettled or water bathed in a washtub over an open fire in the back yard. Guess she was just lucky, cause they all survived. I thought I was pretty progressive with my Ball Book, but there's some scary stuff out there now. I used to spend my vacations pressure canning salmon on a vintage gas stove in a cabin on the lake while DH went fishing, surprisingly the marriage survived too. Annie's salsa rocks, just made the fourth batch! Put that in the Ball Book !

Please correct me if I'm wrong, but the recipe would look something like this with your "tweaks" (I have doubled the tomatoes, or rather left them the same while halving the other ingredients and leaving out the hot peppers, so this still makes something like 5 pints rather than 10 which would not fit in *my* BWB): Tweaked recipe (makes app. 5 pints?) Ball Zesty Salsa Recipe (from freshpreserving.com) 10 cups chopped cored peeled tomatoes (about 25 medium) 2.5 cups chopped seeded green bell peppers (about 2 large) 2.5 cups chopped onions (about 3 to 4 medium or 1 large) 5 oz cider vinegar (or lemon/lime juice)* 1.5 cloves garlic, finely chopped (app. 1.5 tsp) 1 Tbsp finely chopped cilantro 1/2 Tbsp salt 1/2 tsp hot pepper sauce, optional *Note this is halving the acid, as previously noted this may be borderline, it would be safer to increase the acid to compensate for the "increased" volume of tomatoes. NCHFP acidification for tomatoes is 1 Tbsp per pint (2C), so that would be 2.5Tbsp (1.25 oz) of lemon (or lime) juice for the 5 "additional" cups, assuming the original recipe had *just* enough acid (vinegar) with no wiggle room. If using vinegar it would be 5 Tbsp (2.5oz) additional, for a total of 7.5oz (so say 1C). There is still the density issue as Dave said - though I think that "substituting" 5 cups of tomatoes in the (halved) recipe for 1 1/4C peppers would help, it really depends on what kind of tomatoes you're using. Now, compare above "recipe" with Annie's tested/approved recipe: Annie's Salsa Recipe 8 cups tomatoes, peeled, chopped and drained 2-1/2 cups onion, chopped 1-1/2 cups green pepper, chopped 3 - 5 jalapenos, chopped (app 1/4C) 6 cloves garlic (may be reduced) 2 teaspoons cumin (may be reduced) 2 teaspoons ground black pepper (may be reduced) 1/8 cup canning salt (or to taste) 1/4 cup fresh cilantro, chopped (may be reduced) 1/3 cup sugar (optional) 1 cup 5% apple cider vinegar 2 cups (16 oz.) tomato sauce 2 cups (16 oz.) tomato paste Mix all ingredients, bring to a boil and boil for 10 minutes. Pour into hot pint jars, seal and process in a boiling water canning bath for 15 minutes. Makes about 6 pints Annie's does have about 3/4C less low-acid ingredients and 2C less tomato, plus adds tomato sauce to thin it out (though my notes say that it is optional - if you're using beefsteaks and not paste tomatoes it may be thin enough, you may want to add more paste and less/no sauce, just make sure it's soupy). See the thread linked below for complete notes (malna, I had made the same notes myself, took a lot of digging through old threads!). That thread also has link to NCHFP salsa acidification guidelines. All in all, I think you're better off just trying Annie's.

Remember soy sauces differ significantly, so depending upon the brand/type originally used in recipe development the final flavor might have been considerably milder. If there's an Asian market anywhere in the area you might ask if they ever do "tastings" of their products. Or purchase the smallest possible size until you hit on one that at least isn't so obnoxious. Pineapple is high-acid so if anything, as long as you continue to maintain a thinner sauce, there's no problem adding it. On another note, on that Idaho recipe I'd be inclined to reduce the ClearJel by half. That stuff has incredible thickening power and many of the "approved" recipes are just too viscous for my taste. Alternatively, leave thickening out and plan to thicken if desired once the jar is opened. Personally I think that would be a more versatile alternative - more possibilities for use as a marinade, etc.
