Another easy quick sauce.
In a small saucepan combine:
1/2 cup date sugar (agave nectar, honey, or use 1/2 teaspoon monk fruit powder)
2 tablespoons arrowroot
3/4 cup water
zest and juice (1/4 cup) of 1 lemon
Whisk over medium high heat until thickens, about 3-5 minutes. If a richer taste is desired, when thickened, whisk in:
2 tablespoons avocado oil (or vegan butter or margarine)
