I just discovered adding lime or lemon juice to water to liven it up a bit, and I love it! The only problem is, limes and lemons are ridiculously expensive here in Australia. I live in a complex that has its own herb garden and they included a kaffir lime tree, but there's no regular lime tree. So I can get a supply of kaffir limes for free. Would kaffir lime leaves or the juice of the lime be good as a replacement for lime? I have no idea. How do kaffir limes differ from regular limes?
I'm not very familiar with what you're doing... but I can say that you don't marinate fruit or limes. The correct term is macerate I believe. Here is a recipe to get you started. 2 teaspoons granulated sugar 4 key limes, halved and seeded, or 2 small, juicy limes, quartered 2 ounces cacha?a Sprinkle the sugar over the limes, and muddle them in the mixing glass part of a Boston shaker until the sugar is dissolved and the lime juice is released. Pour an old-fashioned glassful of cracked ice into the mixing glass, add the cacha?a, and shake to incorporate. Return all the contents to the old-fashioned glass. Caipirissima: Use rum in place of the cacha?a. Caipirosca .
