Have you ever brought a garlic bulb home and had it fall apart? Or gone to chop up a clove, and it was all dry? Let me share some hints with you, so that doesn't happen again...
1. don't buy a bulb that is falling apart or starting to open up - it's old
2. bulbs with pink-purplish bits are fairly fresh (picked recently)
3. toss the bulb in the air - the faster it comes down, the younger it is (older bulbs are lighter and don't fall as fast)
