Pour into a glass drizzled with honey and garnish with more walnuts (optional).
*I used a mix of low-fat cottage cheese and plain low-fat yogurt, but you could do all of one instead. For a non-dairy option, try coconut yogurt or an equivalent amount of any non-dairy milk. *Sub other sweeteners, such as honey, maple syrup, agave, splenda, or truvia. *Coriander and cardamom have a strong taste, so add a little at first, sample, and then add more to taste. *Questions about substitutions, equipment, or troubleshooting? Check out our Recipe FAQ page. *Nutrition information is a rough estimate calculated without optional stevia or honey.
