How to select good garlic at the store and keep it fresh?As a French raised in Languedoc I have been using lots of Fresh Garlic in my cooking over the last 60 years, both in France and in Chicago, and I always keep it in a French-made, probably by a Provençal artisan, earthenware or terracotta pot. It is vented by holes on its sides, and keeps the garlic at a more or less constant temperature. The essential quality is that this kind of vessel protects the original freshness of the heads of garlic from light, humidity, and high temperature. I dislike Chinese and South American "fresh" garlic, both bulk or packaged. Chinese garlic is the most common import in the US. But it is said to be produced and processed in terrains irrigated by very (not treated)unclean and polluted water. Sometimes I find decent fresh garlic from Spain at Valli's. To me the best, of course in summer, is the locally produced garlic that I buy at the Evanston farmers market. Especially when they have the purple kind. But my favorite one by far is the Northern Californian that I buy every year at the MountainView's (CA) farmers market. It comes from local farmers, usually in Central Valley, or from the Gilroy area, nicknamed " The garlic capital of the world". Christopher Ranch is the largest and most well-known producer there. You can buy 2 pounds bags of that brand of fresh heads at Amazon.
In the winter time I find decent Californian, relatively fresh, heads of garlic at Trader's Joe. It costs only 49 cents a head.
If it happens that fresh garlic has grown a green sprout inside, I use a very sharp paring knife to cut it in half and to remove it.
