Can I cook a whole garlic head without peeling it at all? I am concerned that there may be bugs by the root. And if permitted what would be the procedure to clean it to be able to do so?

 

You may not, as garlic must be checked since it is sometimes infested.

The peels have insects, but the cloves, though, are generally clean.

Therefore the peels should be removed and discarded. And the cloves should be rinsed with a strong stream of water and may be eaten.
