Simple to make from scratch. Rich and nutty flavor.
Ingredients
1 cup California walnut halves, rinsed (about 4 ounces)
3 cups water, plus more for soaking the walnuts
1 tablespoon honey or agave nectar
1 teaspoon pure vanilla extract
Pinch of kosher salt
PREPARATION
Place walnuts in a bowl and fill with enough water to cover by 1 inch. Cover and set aside at room temperature to soak at least 1 hour to 12 hours (this helps remove some of the tannins and makes them blend smoother).
Drain walnuts and rinse thoroughly. Combine walnuts, 3 cups water, honey, vanilla, and salt in the carafe of a blender then blend on low until very smooth, at least 2 minutes.
Serve as is, or if you desire a smoother milk, pour through cheesecloth or a coffee filter to strain. (Will last up to 5 days in the refrigerator.)
