I used to buy whole garlic bulbs at the supermarket.
For awhile, I used the minced garlic that comes in a jar.
Then I found "Stan's" in the "Strip District" (as in it's laid out in a long "strip" - nothing to do with strippers) that sells green cloves in BULK for cheap.
That's what I bring home to process and freeze.
SOMEDAY I will plant my own and dry it, but I have more pressing matters at this time.....
IF I used it raw, It would be more important to grow my own.
I mainly eat beans, peas, and lentils (because that's what disability checks and food stamps can afford) so I use a frozen rough tbs or two in the mix.
