Pickles!

It is very easy. I usually make cooked pickles. Just make a salty brine (salt + vinegar + water) with flavorants (garlic, peppercorns, herbs, etc). I usually use 2 cups water, 2 cups vinegar and a 1/4 cup of kosher salt. Stuff a jar tight tight with the cukes (cut or whole) and pour the boiling brine over it, then close the jar loosely and put it in a big pot of boiling water to simmer for another 20 minutes. Pickles in 2 weeks.
