Lemon or Lime Ice Cream

Preparation

1. Step 1

   In a food processor, pulse together zest of 3 lemons or limes with granulated sugar until smooth and brightly colored.

2. Step 2

   In a small pot, simmer heavy cream, milk, citrus sugar and salt until sugar completely dissolves, about 5 minutes. Remove pot from heat. In a separate bowl, whisk yolks. Whisking constantly, slowly whisk about a third of the hot cream into the yolks, then whisk the yolk mixture back into the pot with the cream.

3. Step 3

   Return pot to medium-low heat and gently cook until mixture is thick enough to coat the back of a spoon (about 170 degrees on an instant-read thermometer). Remove from heat and allow custard to steep for 30 minutes.

4. Step 4

   Stir in the juice and zest of the remaining lemon or lime. Strain through a fine-mesh sieve into a bowl. Cool mixture to room temperature. Cover and chill at least 4 hours or overnight.

5. Step 5

   Churn in an ice cream machine according to manufacturer’s instructions. Serve directly from the machine for soft serve, or store in freezer until needed.
