I don't know where most of you live, but for me, situated as I am in the mountains of western North Carolina, not much is growing here in March. The farmer's markets don't even start up again until mid-April. Even then, for the most part all you'll find are leafy greens and the occasional radish on the farmer's tables, with maybe a stalk or two of rhubarb, if you're lucky.
Which is why all-things-Allium seemed like the obvious choice for this month's Can Jam. From tender, green scallions, chives, scapes, ramps, and leeks to papery, husky onions, shallots, and garlic, the Allium family is the vegetable world equivalent of the guest who shows up at 6:50 p.m. for the cocktail party that begins at 7:00-by showing up early and motivated as all get out, they get the party started. Alliums are ready for the good times to begin again.
Much like last's month Can Jam ingredient, carrots, Alliums are also low-acid foods. Accordingly, once canned and hermetically sealed into an anaerobic environment, latent botulism spores found on Alliums can become activated and thrive. I don't want that. You don't want that. No one but the botulism spores wants that. But you just can't let them win! You must resist! Refer to Tigress' erudite tutorial on properly acidifying low-acid foods for safe water bath canning here.
