Raw Lime Cordial*
1 3/4 cups sugar
First, trim the ends off the limes, then peel them with a paring knife or vegetable peeler, removing as little of the white pith as possible. Next, juice them into a measuring cup. This will yield around 1 3/4 cups of juice. Pour the juice into a wide-mouthed, non-reactive container, then mix in an equal amount of sugar and stir it into the juice until it is completely dissolved. Next, express the oils in the peels by squeezing them in your hands over the juice mixture before dropping them into it, stirring it to release more of the oils, covering it, and infusing it in the refrigerator for 24 hours. The next day, strain the mixture into a carafe, yielding approximately 2 1/2 cups.
