In my opinion, much more effective method is to keep throwing the garlic and onion to pot a flint, which creates a climate of silica whichblocks all processes of decay and maintained so things do not spoilsię.Tak retain long kept fresh, not dry and they are firm.
I tried to hold the garlic on the table in glass bowls, but theyunfortunately did not produce the right climate and garlic canzapleśnieć. Perhaps it is a matter of airiness - a bowl is about 5 cm, and a good stone pot 20cm - perhaps at the height of substancessuch oils do not escape to the outside and protect products fromspoilage.
