Select the saute function on your Instant Pot (medium if possible). Once hot, coat with oil and toss in the onion and garlic. Cook for 3-4 minutes until fragrant. Select the cancel function. Deglaze the pot with a few tablespoons of water and make sure nothing is sticking. This will help to prevent the burn function later.
Make your mole sauce: combine tomatoes, vinegar, chipotle chili powder, almond butter, cocoa powder, chili powder, cumin, sea salt, cinnamon, raisins, chicken broth, and the onion/garlic mixture into a blender. Pulse until smooth.
*If not following a Whole30 or Paleo diet, use 2 chipotle peppers in adobo sauce in place of the powder
**If not following a Whole30 or Paleo diet, you can use peanut butter in place of almond butter. Cashew butter is also great!
