Heat a comal over medium heat. Place the whole garlic cloves (peeled) and jalapeños on the comal. Char the vegetables for 5-10 minutes, until there is some charring but be careful not to completely burn the vegetables (the garlic will take less time than the jalapeño).
Remove the stem from the jalapeños.
Place one jalapeño and garlic cloves in a food processor and roughly chop into fine pieces.
Cut the avocado in half, scoop the avocado flesh into a large bowl or molcajete. Discard the pit and peel.
Squeeze the juice from ½ lime on top of the avocado.
Add the salt, garlic, and jalapeños into the bowl with the avocado.
Use a potato masher, fork, or pestle to mash the avocado and combine the ingredients. Continue until you´ve reached your desired texture (creamy or chunky).
Taste. Add more jalapeño if needed.
