Why This Recipe Works

The key to making great key lime ice cream is using high-quality ingredients and controlling the temperature during the churning process. By using real key lime juice and a combination of heavy cream and whole milk, we create a rich and creamy texture that's balanced by the tangy flavor of the key limes.

Another important factor is the temperature at which we churn the mixture. By keeping the mixture cold, we can create a smooth and even texture that's free from ice crystals. This is achieved by using a mixture of ice and rock salt to lower the temperature of the ice cream maker.

Finally, the resting time is crucial in allowing the flavors to meld together and the texture to set. By letting the ice cream rest in the freezer for at least 2 hours, we can create a smooth and creamy texture that's perfect for scooping.

In a medium saucepan, combine the heavy cream, whole milk, granulated sugar, and fine salt. Heat the mixture over medium heat, stirring occasionally, until the sugar has dissolved and the mixture is hot but not boiling.

4
Remove the saucepan from the heat and stir in the key lime juice and vanilla extract. Let the mixture cool to room temperature.
5
Cover the mixture and refrigerate it for at least 2 hours or overnight.
