I love the taste of all citrus fruits, but there's something especially intense in the flavours when it comes to lime. This recipe revels in the taste of lime and it's really very easy to make. So, here's what you need:
- 6 juicy limes
- 2 cups water
- 1 1/4 cups sugar (and another 1/4 cup if you want to reduce the lime intensity a little)
- 2 tbsp rum (or vodka)
- 1/4 tsp pure vanilla extract
Mix water and sugar together and heat at medium to melt the sugar into the water. Once melted, remove from heat and let cool. You're basically creating a very thin sugar syrup.
While that's going on, zest half the limes. Then juice all 6 limes, getting as much of the liquid as you can. You can mix the zest and the juice, it's all going in the mix anyways. You should have about 1 cup of juice. Then add to the juice the rum and the vanilla.
Note: The purpose of the rum is to change the mixture enough to prevent the sorbet from becoming an ice cube, you want to be able to scoop it. If you don't want to use alcohol, then you can create an Italian meringue from the whites of a couple of eggs. The meringue ensures the egg is cooked which is the safest course.
Once the sugar water has cooled, mix in the lime/rum/vanilla mix and stir thoroughly. Poor into a freezer safe container (should be at least 4 cups in capacity) with a lid and freeze.
After about 3 hours, give the mixture a good stir, scraping the sides of the container, and return to freezer. In another 3 hours, pour mixture into a blender and blend thoroughly. It should be slushy like at this point. Place back in the freezer and continue to freeze until it reaches an ice cream-like consistency. Serve and enjoy, keeps for a while in your freezer.
You can substitute limes for other citrus if the juice volume is roughly comparable. You might exclude the vanilla for some choices, it mixes well with lime, not so much with grapefruit.
