No dairy, no eggs, no problem! This vegan ice cream gets its velvety texture from avocados and coconut milk.
Mash avocados (you should have about 1 1/2 cups). In a blender, combine avocados, coconut milk, lemon zest and juice, sugar, salt, xanthan gum, if using, and 1/4 cup water. Blend until smooth. Refrigerate 1 hour or up to overnight. Freeze mixture in an ice cream maker according to manufacturer's instructions. Transfer to a loaf pan and freeze, wrapped in plastic, up to 1 week. Let soften at room temperature 20 minutes before serving.
