Watermelon Sorbet
Because no two batches of fruit have the same sweetness, it’s important to adjust the mix before freezing. This will affect more than flavor because sugar lowers the freezing point of water; so the sweeter your mix, the slushier your sorbet. Too little sugar and the sorbet will be icy hard. Some chefs use a saccharometer (which gauges a liquid’s density by how much of the instrument floats above the surface), but a large uncooked egg stands in quite well (see step 4). Watermelon is one of the simplest flavors to make, since it requires no added water. Follow the amounts in the chart on page 485 to make the suggested flavor variations. When using only juice, you can skip the first step. Citrus fruit can be squeezed by hand. For the kiwi and pineapple sorbets, you will need to add fresh lime or lemon juice along with water in the first step. All liquids should be strained into a deep bowl or plastic container as directed. If desired, add up to 3 tablespoons of other flavorings such as liqueur before adding the simple syrup.
