Chile Pepper Vodka
Choose 3-6 perfect red Serrano chilies. Leave whole, but cut a slit down the length of each (what to for getting the spicy goods into the vodka). After the vodka is flavored to the level of your taste the "pickled" peppers can be used in cooking.
It takes about one week for the chile magic to show up in the vodka. The longer the chilies are left in, the bolder the heat. You can remove the chilies at whatever point, or leave in.
