Step 1

Start by zesting the limes, set aside. Now juice the limes, orange, and lemons. Strain, and measure out 1 1/3 cups of fresh juice (combine 3/4 cup fresh lime juice, 1/4 cup fresh orange juice, and 1/3 cup fresh lemon juice) and refrigerate.

Step 2

Make a simple syrup by combining the sugar and water in a small saucepan over medium heat. Stir and cook until the sugar has dissolved, remove from heat, and when cool enough to handle, transfer to a jar and refrigerate until cool.

Step 3

Combine the citrus juice, simple syrup, and yogurt in a medium bowl. Mix, using a hand blender, until smooth.

Step 4

Freeze using manufacturer’s instructions in an ice-cream maker, adding the salt and lime zest when the sherbet is the consistency of thick frosting. Serve or transfer to a freezer immediately.
