Although this drink is called a "limonada frozen" in Spanglish, it is actually a frozen limeade drink. It is very tart and refreshing.
The addition of some passion fruit pulp or passion fruit juice is delicious mixed into this drink. An excellent alcoholic version of the limonada frozen is the frozen pisco sour, which is made with Peruvian pisco brandy.
In some parts of Latin America, limes are grouped into the category of tart citrus fruits known as limones (lee-mone-ayes), since lemons are not widely available. South American limes are smaller, juicier and more tart than the larger Persian limes that are often sold in the US. Look for small limes with thinner skins (often imported from Mexico) or key limes for making this recipe.
- 1 cup sugar
- 1 1/2 cups water
- Pinch of salt (optional)
- 1/2 cup key lime juice (from about 8 small key limes)
- 6 cups of crushed iced
- Place limes in the microwave for 20 seconds on low power (or until they are just warm, not hot to the touch) then roll them around a few times on the counter, while pressing down with the palm of your hand.
- Bring the water and sugar (and salt if using) to a boil, stirring until the sugar is dissolved. Remove from heat and cool.
- Mix the sugar water, lime juice, and ice in a blender, and blend until well mixed and slushy. Serve immediately in tall glasses.
