I tried it with some fresh garlic from ASDA and it didn't work. The garlic head is easy to break into cloves (I already know how to do that) but the purplish-coloured garlic cloves seem to have very sticky skin. I resorted to my usual method of bashing the head to release the cloves then cutting the blunt end off ecah clove and bashing them all again to release the skins. If you watch a Jamie Oliver video he often just sticks each clove into a garlic press, skin and all - the skin doesn't go through the holes. If you're gong to blend it anyway, WTH, a bit of skin doesn't matter.
