Internet research led me to numerous copycat recipes for the sauce, which is available in its authentic form from Café Yumm! The recipe I used (set out in full below) produced an excellent sauce, intensely almond and lemon-flavored and resembling tahini, which is sesame seed-based.
What to do with the sauce? You could use it as a dip with pita chips or bread or make Yumm Bowls, a healthful, hearty dish that they make at Café. The Café's blog has a video demonstrating how a Yumm! Bowl is made: atop brown rice, add a ladleful (I used 3/8 cup) of Yumm! Sauce, then small quantities (I used 1/4 cup each) of black beans, chopped tomatoes, salsa, grated cheddar and sliced black olives, a couple of slices of avocado and a dollop of sour cream; then garnish with cilantro (I sprinkled sesame seeds). Tasty, simple, vegan and gluten free.
Here is a picture of my version.
- 1/2 cup oil (preferably canola oil)
- 1/2 cup almonds
- 1/3 cup nutritional yeast
- 1/3 cup garbanzo beans
- 1/4 cup soybeans (or use 1/2 cup silken tofu if needed)
- 1/2 cup water
- 1/2 cup lemon juice
- 2 garlic cloves
- 1/2 tsp salt 1 tsp curry powder (or use less and supplement with dried basil or similar herbs)
