Almond and Sweet Potato Sauce

A Casa de Luz sauce strikes again. With goodness that is!! Man, those people know how to make simple food taste awesome. I halved the recipe and used only one sweet potato, but instead of using 1/2 cup of almond butter, I used just over 1/4 cup and found it to be plenty.
The sweet potato I used, must have been particularly sweet. The Monster tasted the sauce and thought I'd slipped in some dulce de leche! A friend just gave us a tub of the stuff and honestly that probably wouldn't be beneath me by any means. You can adjust the sweetness by adding more lime juice, etc. if you want. One of these days I'm going to have to buy Casa's durn cookbook instead of trolling the internet for their recipes. :-)

Almond and Sweet Potato Sauce:
(Casa de Luz)

2 medium sweet potatoes (about 3 cups)
1 cup unsalted roasted almond butter (used less...just over 1/4 cup for half of the recipe)

2 tsp. shoyu or tamari

2 Tbs. lime juice

Pinch of sea salt

Filtered water as needed

Update:
When we ate the rest of the sauce the next night I added a touch of rice wine vinegar, a bit of sambal oelek (chili sauce), and some more lime juice. YUM.

Wash sweet potatoes and cut into 2" chunks. Place in a heavy pan with 3/4 cup of water. Bring to a simmer, add pinch of sea salt, and cover (I roasted the sweet potato wrapped in foil at 400 for about an hour, then peeled once cool).
Let potatoes simmer over low heat until tender. Remove from heat, reserve any leftover cooking water, and allow to cool, Leftover baked sweet potatoes may be used instead.
Place cooled sweet potatoes, almond butter, shoyu/tamari, and lime juice in a blender with some of the water and puree until smooth. Add a more water until you achieve a consistency you're pleased with. Serve over greens or grains. I served it with lemon and herb baked tofu over quinoa and braised kale.
