growing and storing a year of garlic

MY HOMEGROWN CROP OF GARLIC GETS ME TO ALMOST FEBRUARY, and then it’s just not what it used to be. You know how it goes—you’ve bought late-winter cloves that start to sprout and just don’t feel as firm or weigh what they did before time took its toll. I don’t have a perfect storage spot; considering that I do quite well. But this year I’m laying in a supply in the freezer, too, following safe, sane methods—no, you cannot just pack it in oil and refrigerate! My tactics for growing, harvesting and enjoying a year of garlic. Both softneck and hardneck types are welcome here, by the way—dare I ask which camp you’re in?

Welcome to Garlic Week, edition Number 7 of the Summer Fest recipe swap (details of how this annual online harvest event works are at the bottom of the page, along with links to garlicky ideas from all my collaborators).

Like any bulb, garlic is a little particular about above-ground storage conditions. Once it’s fully cured, commercially grown garlic is stored at about 32 degrees and 65 percent humidity, and depending on the species and variety, may last six months or even longer. My very primitive basement—an old stone foundation, no heat except for the little bit given off by the furnace—is a bit too warm, but it’s all I have. The garlic hangs in mesh bags from the rafters (as do my onions).

Into the Deep Freeze

THIS YEAR I’M FREEZING a portion of my harvest, trying a few methods gathered from university extension services and my collection of preserving books. Important note:

Even at below 40 degrees, such as in the refrigerator, you run the risk of harmful bacteria forming after about a week, including spores of Clostridium botulinum, the cause of botulism. Oil-packed peeled garlic sold in the market contains a preservative, such as citric acid. Achieving safe preservation this way is best left to commercial packers.

(Ditto with your oil-packed sun- or oven-dried tomatoes—something I shudder when I think I did for many years. Better to dry the tomatoes, pack them crisp in airtight bags, then soften a week’s worth at a time in oil before using. Herb-infused oils, particularly those with garlic, run the same risk.)

The trouble: bacteria can form in water droplets trapped within the oil, says the National Center for Home Food Preservation. Plus garlic is a low-acid food (therefore more prone to bacteria formation), and the low-oxygen conditions that bacteria loves are ideal thanks to the oil packing. A perfect storm.

  • Whole, unpeeled cloves can be frozen as is, then thawed and used as needed. Last fall I also peeled a batch, tossed them lightly in oil and froze in bags. Looking good!
  • I’m more optimistic about the convenience of making a log or small brick of chopped garlic—not unlike my parsley logs—and slicing off just what I need for a recipe.
  • Likewise, a puree of garlic and olive oil can be frozen like my other pestos, in cubes or small containers.  (The University of California at Davis recommends 1 part garlic to 2 parts oil, for a sauté mixture that remains safely frozen but is soft enough to scrape the needed amount off at any time.)
  • With all freezer methods, freeze immediately after preparation; do not refrigerate or store at room temperature even briefly first.
  • Sometimes in midwinter, if I see that I have too much garlic and onions still in storage and worry they won’t last, I freeze them this way. The same could be done with a portion at harvest time.

The Cultivation of Allium sativum

GARLIC COULDN’T BE EASIER TO GROW: Plant like any bulb in fall; topdress with organic fertilizer when shoots start really growing in spring; keep it well-watered during active growth; weed well. The details:

Hardneck Versus Softneck: Which to Grow?

SOFTNECK GARLIC (Allium sativum), the common type of supermarket familiarity, has a row of largish outer cloves and a row or two of inner small ones. It would keep better than what I grow, but I like the bigger (though fewer-per-head) cloves of the hardneck kind (shown above), which also has the bonus of producing scapes (flower stalks that you cut off and eat before bloom) in May or thereabouts.

My reason:  Hardneck garlic (Allium sativum var. ophioscorodon) is better-adapted to Northern winters (its long roots–or at least before I trimmed them after curing–hold it in the heave-and-thaw ground especially well), and frankly I just hate all those tiny inner cloves of softneck at peeling time. Nor does comparatively puny softneck make as nice a roasted head of garlic as the bigger-cloved kind.

How Do the Varieties Compare?

HAVE A FAVORITE GARLIC? Add your ratings to Cornell’s “Vegetable Varieties for Gardeners” variety-comparison database of more than 70 garlics. Unlike tomatoes and squash, for instance, which have loads of ratings from commenters, the garlic department could use our feedback!

Time to Order: Garlic Sources

OCTOBER IS PLANTING TIME, since about a month before frost is in the ground is perfect timing. Order now—and in coming years, order even earlier for best selection. Eventually, if all goes well, you’ll achieve garlic independence (where you have enough heads for eating and to supply your own “seed” cloves). I got there last year.

A Garlicky P.S. of a Book Giveaway

NEW YORK TIMES FOOD COLUMNIST Melissa Clark’s latest cookbook debuted this week, and more than 10 percent of the 150 recipes in “In the Kitchen With a Good Appetite” feature garlic in their titles. True; I counted.

Over on my story about the delicious new book I’m offering a chance to win one of two copies (if you get there by September 12, 2010 at midnight). Can you almost taste the Crispy Tofu With Garlicky Peanut Sauce and a side of Garlicky Swiss Chard now? Heaven. Like I do, Clark adheres to the philosophy that “mashing anything  green with garlic and oil” is a good idea. Even fennel fronds, she said just the other day. Like I said, enter here.

    Such great information…I am learning all the time. I just recieved my order of garlic to plant. Last year I planted in the spring with the rest of the garden…..let’s just write that off as a mistake and forget about it…..Oh and did I mention I have garlic loving squirrels in my garden. So now they go into the enclosed and electric fences garden. Here hoping for a vampire free next summer…thanks for the info.
