My whole unpeeled garlic has turned "very soft". Its internal texture has changed too.
What are the indicators of non-edible whole garlic?
There are three signs you want to look for on garlic that indicate you may not want to use it:
Good garlic should be quite hard when pressed with your fingers, and preferably is not sprouted. Some people even remove the green core of partially or beginning to sprout garlic when they prep.
