Home Canning for the Newbs, by the Newbs.

Abstract: Despite my best attempts to consume and/or give away all the squash coming out of my garden, I still find myself in a surplus situation. Desperate to dispatch the last of my zucchini, I've turned to home canning to preserve my bumper crop with a method that renders said cucurbit a dead-ringer for canned pineapple. My kids' breakfast smoothies will never be the same.

Purpose: Last year, a friend of mine slipped me a recipe for zucchini pineapple. What the hell? Is it a preserves? Is it supposed to be sweet? I had no idea. I had to research. While flipping thru my trusty copy of UAF's Zucchini A to Z, I discovered that the preparation is actually a classic from the home-canning oracle that is the University of Georgia Cooperative Extension. This recipe wasn't some novel creation concocted in someone's out-building. This here was a tried and tested recipe; which after growing up with home-canned food and having never head of it made it all the more intriguing.

I have a confession: I try like crazy to avoid canning, because I despise the tedium of it all. Massive amounts of prep, doing dishes, and inflexible recipes in the name of safety are all buzz-kills when measured up against how I cook. My first option for preserving food has always been the freezer, but I'm not at all keen on the texture of zucchini from the freezer. The cell structure of the zucchini seldom survives the torment of a trip back above freezing point, and what was once a bag of veggies ends up looking more like a water balloon. There was really no choice; if I was gonna keep all this zucchini, I needed to can.

I'm most certainly a novice preserver, but I can sure follow directions. As I was boning up on my procedure, it struck me that most home-canning methods always seemed to be described separate from the actual recipes. This is fine and all for folks that understand preserving, but frankly I think it's a barrier to people who are new to this rewarding pastime. In that context, I've decided to document the often-intimidating technical aspects of this super-simple recipe that transforms those big-honkin' runaway zucchini into something that has the taste and texture of canned pineapple tidbits.

Recipe: Jump to the detailed recipe. (or, keep reading for the gist of it) -

  • 15 lbs zucchini That's pre-processed weight; about nine lbs after peel and pith are removed.
  • 46 fluid oz canned pineapple juice (usually one big can)
  • 1 1/2 cups bottled lemon juice Not fresh. Gotta be bottled for safety.
  • 3 cups sugar

  • Peel zucchini, remove seeds and pith. Either cut into half-inch cubes or shred. Mix zucchini with other ingredients in a large saucepan and bring to a boil. Simmer 20 minutes. Fill hot pint or half-pint jars with hot mixture and cooking liquid, taking care to remove any air bubbles while leaving a half-inch of head space. Wipe jar rims, top with lids and rings. Process in a boiling water bath for 15 minutes, remove and let cool to room temperature to seal.


    • As far as supplies are concerned, what you really need to start isn't much:

    • If you don't have a proper canning pot, a huge stock pot with a wire rack on the bottom is acceptable. Jars cannot rest on the bottom of the pot, and will need to fit comfortably without knocking into each other.
    • Traditionally, water bath canners have been a no-no on a flat-top stove. I'm not gonna tell you how to work your oven, but I will tell you on my particular model, the burner I use for large pots pumps 3800 watts (twice normal wattage). I figure if it can handle that kind of thermal stress and my water gets to a rolling boil, I'll probably be ok. Bottom line: do your research.
    • If you're gonna can at home, be ready to do some dishes. I can't over-emphasize how important it is to keep your stuff clean. Those who have made yogurt and beer know the extent of clean I'm talking about.
    • To clean my glassware, I like the oxygenated, non-chlorinated cleaning powders (Oxi Clean and its ilk) for the lack of perfumes and chlorine. I figure that smelly stuff trapped in a sealed environment has the potential to impart off-tasting flavors into a product over time.
    • Start the water bath in that large pot early, as it'll take a while to get it to boiling. Measure for two inches of water over the tops of the jars, and then be ready to top the pot off with more hot water as it's gradually lost to the ether. Keep the jars in the water bath as it comes to a boil so they stay plenty hot for when it's time to fill. Btw, you'll need your jar lifter to handle that glassware safely.
    • Once the water bath is started and dishes are done, turn your attention to dismantling your zucchini. The recipe says you can shred or dice. I've tried both, and I prefer the texture of the dice. Re: the skin, I hate to say it, but it's gotta go. You're losing vitamins, but you'll get some back as the squash is infused with pineapple juice.
    • The recipes you'll find in home canning that require lemon juice never ask for fresh-squeezed. Lemon juice in canning is a pH regulator; used to keep microbial maladies at bay. Bottled juice always has a consistent acidity printed right on the label. Fresh squeezed, not so much...
    • When pulling hot jars back out of the bath to fill, make sure they set on a surface that won't suck the heat out of the jars and possibly break them. Wood cutting board = great; granite countertop = not.
    • The space on the jar where the threads start is also where the jar's “head space” begins. Head space is necessary to ensure that gas has a means to cleanly escape as a vacuum is established in the jar. Fill the jars with squash to just below the head-space demarcation, and fill with additional liquid so as to make sure all product is submerged. You can tell by my pictures that I was a bit stingy with my liquid. You can do better than me.
    • After filling, wipe those jar rims clean. Any lip with a ding or chip in it should not get the bath. Top with a brand new lid and screw on a ring to hold the lid in place (used rings are fine). Thread the ring on until there's enough resistance that the whole jar just starts to spin on your work surface. Tightening is unnecessary and unwanted.
    • On the topic of lids, many manufacturers say to pre-soak the lids in hot or simmering water to prep that seal. I did not, and mine still sealed up great; however, you should probably follow the manufacturer's posted directions to be safe.
    • When moving the jars back to the bath to finish, make sure they stay fairly level when you're moving them around. You want to keep the headspace inside the jar dry for a good seal. Once they hit the water, you'll see plenty of air bubbling up out of the jars, and that is a good thing. That expelled air is what creates the vacuum in the jar as it cools. Lid that pot up to conserve heat and “process” (that means boil) for the directed time in the recipe for the size of jar you're using. In this case, it's 15 minutes for a pint jar.
    • As the processed jars are removed back to the cutting board to cool, you'll start to hear that lovely “pop” as the jars begin to seal as they cool. This little noise is your biggest reward for all that friggin' work.

    Results: Infusing a mild veggie like zucchini with the tart pungency of pineapple really needs no explanation when it comes to taste. If you're eating this stuff out of the jar, treat it like canned fruit cocktail, as the consistency of the zuke is somewhere between canned pineapple and canned pears. I use it in my kids' smoothies at breakfast in lieu of applesauce for an added bit of fiber and vitamin C. Other possible options might include a mix-in for carrot cake or maybe even the base for a “fruit” salsa with some chipotle chiles and green onion.

    This ain't the voice of experience talking here, so please don't take my ramblings as gospel. What has been documented in the confines of this URL is a procedure where thoughtful precaution and planning have been considered. All the while, mistakes still seem to rear their ugly head. I'm the first to admit that I'm still a home-preserving greenhorn, so any constructive criticism is welcome.

    Calling this recipe “easy” is a bit of an understatement. However, following an easy recipe enables a novice canner to focus on the method itself, which makes this recipe a great start for anyone looking for an easy introduction to home canning.

    Notes: Covering my ass here, the procedures I've described here are taken from tried and tested sources. As much as I like to experiment with my food, the realm of preserving is a poor place to flex that creativity. Stick to the recipes and methods provided by established sources, and if something you put up looks, smells, or tastes questionable, play it safe and toss it. After all, the jars are reusable, aren't they?
