You are probably wondering why basil is on this list. After all, you can find fresh basil leaves in the refrigerated area at the supermarket, is what you are thinking right? Basil is actually not resistant to cold temperature and the plant will wither in your refrigerator before you know it. Also, the plant will absorb the scent of the other foods stored in your fridge. To keep your basil fresh for a longer period of time, the best thing you can do is to treat it as a regular plant or flower, and put the stem of the basil in a glass water. If after preparing your meal you find yourself having some basil left over you can blanch the leaves and put it in your freezer. This way you can enjoy your basil leaves for a lot longer!
