Ingredients
Method
Roast the Garlic
- Preheat the oven to 375°F.
- Cut the top third from the whole bulb of garlic to expose the cloves inside.
- Place the bulb onto a square sheet of aluminum foil.
- Drizzle the exposed cloves lightly with kosher salt, black pepper, and a pinch of dried oregano leaves.
- Wrap the foil tightly around the garlic, leaving a small opening at the top to vent the steam.
- Place the foil packet onto a rack in the oven and roast until the cloves are deeply golden and trying to escape their papery skins, about 1 hour.
- Remove from the oven, cool slightly, and squeeze the roasted cloves out of their skins. (Reserve 6 cloves for the guacamole and refrigerate the rest for up to a week).
Grill the Ingredients
- Heat a heavy cast-iron grill pan over high heat.
- Drizzle the 2 tablespoons of olive oil evenly over the hot pan.
- Place the halved avocados, onion rounds, plum tomatoes, jalapeno peppers, and limes directly onto the grill pan, cut-side down.
- Cook undisturbed until deep, dark grill marks appear on all the food, about 3 to 5 minutes.
- Carefully flip the vegetables and limes and cook on the other side for another 2 to 3 minutes, ensuring the onions are fork-tender but the avocados and tomatoes remain firm, not mushy.
- Transfer all the grilled ingredients to a clean work surface and allow them to cool enough so you can safely handle them.
Mash and Assemble
- Use a spoon to scoop the warm, charred flesh from the avocado skins directly into a heavy stone mortar or a large mixing bowl.
- Roughly chop the grilled plum tomatoes, red onion, and jalapenos, and add them to the bowl.
- Squeeze the bright, smoky juice from the blistered limes directly over the ingredients.
- Add the 6 cloves of sweet roasted garlic.
- Season the mixture generously with the ground chili powder, kosher salt, and coarse black pepper.
- Use a heavy pestle or a potato masher to crush and fold all the ingredients together to your desired consistency (mash less for a rustic, chunky dip, or more for a smoother texture).
- Taste and adjust, drizzling in a touch more olive oil for richness or extra lime juice for brightness, if desired.
- Serve immediately with sturdy tortilla chips, or use as an elevated condiment for fish, chicken, or sandwiches.
