Oven: Preheat the oven to 375F and lightly spray a baking sheet with oil (or line with parchment paper.
Prep: Cut the tops off of each eggplant, then cut in half lengthwise. Pierce the outer skin of each eggplant several times with a fork to allow for ventilation while baking. Use 1 tablespoon of oil to lightly brush the cut part of each eggplant, then place cut side down on the baking sheet. Cut the top ½” off of a head of garlic and drizzle a little oil over the top of it. Wrap in tin foil and place on the baking sheet.
Roast: Roast the eggplant and garlic for 45 to 50 minutes, until the eggplant is slightly browned. Set aside to let cool slightly.
Process: Use a spoon to scoop out the flesh of 1 of the eggplants into a food processor with an S-blade attached. Add the roasted garlic cloves (they should squeeze out easily), 1 tablespoon of remaining oil, sesame oil, cumin, miso and rice vinegar. Process until smooth, about 30 seconds
Make it Chunky: Scoop the flesh of the remaining 2 eggplants into the food processor and discard or compost the skin. Pulse the dip a few times, until the eggplant is incorporated but the dip is slightly chunky. Adjust any seasonings to taste, if necessary.
Serve: Transfer the dip to a plate or serving bowl and swirl the top with a spoon. Drizzle chili crisp and oil over the top of the dip and garnish with fresh herbs and serve.
Store: Store any leftovers in the refrigerator for up to 5 days. The dip can be served cold, or you can warm it up.
