I used to buy it in a jar but the taste is not the same. As it is only me, I just buy one or two bulbs at a time and keep in the fridge. There is nothing like the smell of fresh garlic hitting the hot olive oil in the pan!! Now if they could put THAT smell in an air freshener I might buy it.
BTW, if you find yourself with a lot of fresh, separate it into cloves and peel. Throw them in the freezer. To make super easy garlic bread, toast the split loaf in the oven til crispy, rub with thawed frozen garlic cloves, they disappear right into the bread! Then add your butter or oil if you like.
