Zucchini Tomato Salsa (Everyone Needs Salsa, or, What to Do with a Really Giant Zucchini)

OK, definitely should have taken a picture of the giant zucchini. It was roughly two feet long and at least 6-8 inches wide at the big end. One of those white and green striped variety, not the solid green. I looked up zucchini varieties and this was a cocozelle.

It sat in the garage fridge giving me guilty feelings for a long time, at least four weeks after Sweet Hubs brought it home from the RC flying club field where someone said, "Who wants a zucchini?" Hubs knows how I love to preserve foods and that I could turn it into something so he said yes.

It sat so long I thought maybe it would have aged out of utility, but no, when I finally brought it out of the fridge on a sunny Saturday after I had bread in the oven and had made some sourdough discard crackers it was as firm as the day he brought it home. I'm saving seeds from this one to plant for next year.

Speaking of seeds, a summer squash this size has seeds big enough to do something with. Enter this recipe for oven-roasted zucchini seeds. But what about the rest of it?

I'd already made a big batch of Hot & Spicy Zucchini Chutney. I love that so I could see making it again but I've also made a huge batch of Indian Apple Chutney and a smallish batch of Blackberry Apple Chutney and I have some Green Tomato Chutney left from last year. I may be over-chutneyed, if such a thing is possible. I still have jars and jars of pickles from last year, so no pickles, and relish is pretty close to pickles so no relish. Time to mix things up.

Zucchini Salsa to the rescue! I found two similar recipes, both calling for cups and cups of zucchini. Conveniently they also called for cups and cups of tomatoes and my garden produces several pounds a day right now, so I was all set there. 

• Zucchini Salsa from Food.com has half the quantity of tomatoes to zucchini, with onions given in terms of number of onions, not chopped cups, which isn't helpful since onion sizes vary; maybe 1/3 the quantity of zucchini?, and 4 peppers, again without giving chopped cup quantities so I'd guess 2-3 cups or 1/5 the quantity of zucchini.
• Zingy Zucchini Salsa from The Vibrant Veggie has 2/3 the quantity of tomatoes to zucchini, 1/3 the quantity of onions, 1/6 the quantity of peppers.

About the peppers: Mine have been coming on, mostly sweet and a couple with a little heat: Padron, which has a nice tongue-tingling quality without burning, and pepperoncini that's pretty mild. Since pepper heat varies across varieties this seems like a great place to customize to your family's Scoville settings with a mix of sweet peppers and whatever else turns your cranks. I started mild figuring I could adjust with the dried chili spices I'd add later.

The two recipes varied in a couple of techniques. 

To drain or not to drain: After salting the zucchini, onion, and peppers and leaving them to sit anywhere from 3-24 hours, do you drain off the juice or not? One did, one didn't. The juice is more to cook down but with the other veggies in there it carries some flavor. 

After around four hours of soaking I drained off about 2-1/2 cups of liquid and saved it in case I ended up cooking down too much. At the end because I used very juicy homegrown tomatoes it had a fair amount of liquid but I didn't want to turn it into completely broken down mush so I called it done. 

Next time I'd salt only the zucchini and drain that, press it to get even more water out, then add the other vegetables that aren't as watery and start cooking. Or I might even start the zucchini cooking on its own, drain the liquid produced after a while, then add everything else. That would allow a shorter cook time with the tomatoes, onions, and peppers to keep some of the individual veggie qualities without being too watery.

Cook time: The Zippy recipe cooks on a low temp for an hour after bringing to a boil, the Food.com recipe for only 15 minutes. If you want the veggies on the raw side you could go for that short cook time but I wanted more melding of flavors and time for the vegetables to break down a bit. That did result in a lot more release of the liquids but it had a chance to boil off a bit.

Proportions: From the comments on the one at Food.com, a lot of people add ingredients and reduce the acid component willy-nilly before canning. I hope everyone's all right over there. I stayed away from too much ad-libbing and improv and paid attention to ratios of ingredients.

This giant squash produced 16 cups of shredded flesh even after taking out the guts with the seeds. Tracking my adjustments to the two recipes, here's where I landed:

• 16 cups shredded zucchini
• 6 cups diced onion; I had white on hand but yellow would work fine, even red
• 2 cups diced peppers; roughly half sweet red bell, a couple of Padrons,one jalapeño, the rest pepperoncini
• 1/4 c. + 1-1/2 T. salt (any kind, table salt, sea salt, pickling salt) sprinkled over the shredded zucchini, onion, and sweet/hot peppers
• 12 cups diced tomatoes (mixed yellow, orange, red, black, striped)
• 2-2/3 cups apple cider vinegar (could use another that's also 5% acidity such as regular distilled vinegar, red or white wine vinegar; lime juice could also be substituted for part of this if it's 5% acidity)
• 1/3 + 1/2 cup sugar (can use white or brown) (I started with 1/3 cup, which was the amount for 12 cups of zucchini, because I wanted to taste first; I ended up adding 1/4 cup and then another 1/4 cup to offset the vinegariness)
• 8 cloves garlic (when in doubt I add extra garlic; you could increase this)
• 1 T. dry mustard
• 1 T. cumin
• 1 t. chipotle (I like a smoky quality to my salsa; you could use chili powder instead)
• 1 t. chili powder
• 1 T. dried cilantro, optional (dried because I had it; I'd rather have chopped up a bunch of fresh cilantro to throw in but not everyone loves it)
• 1/8 t. cayenne (added after I tasted with all of the above)

Put the drained zucchini in a large pot, add the chopped tomatoes and all other ingredients. Or, as noted above, cook the zucchini on its own for a few minutes to release more liquid, drain that off, then add the other ingredients.

Bring to a boil, stirring occasionally, then reduce to a simmer. Cook for 30-45 minutes or so. Depending how cooked down and thick you like your salsa you may want to adjust the cooking time to less or more.

Meanwhile prep your jars for hot water bath canning. 

My yield with these quantities: 10 full pints, one pint jar not quite full, but more than 1/2 pint so gosh darn, we'll just have to eat that one right away. (Yes, I could freeze it. Hush.) I processed for 20 minutes.
