What's the best way to peel an onion?
Cut the sprout end off.
Place the cut end on the board, slice the onion in half vertically (i.e. place your knife on the root and cut down)
If the outer skin layer is nice and thick, pull it off from one corner. Repeat on other half.
If the outer skin is papery, pull it and one layer of onion flesh off from one corner. Repeat on other half.


If the first layer of onion flesh is slightly dimpled or has a kind of matte finish, it's probably turning 'skinny'. Strip that off too.
