Scoop the chile powder into a blender or small food processor. In a medium saucepan, bring the water to a boil. Pour the hot water over the chile powder, loosely cover the blender or secure the top of the processor, and pulse to create a smooth slurry. Let cool.

If you prefer a straightforward and quick adobo, toss the peeled garlic cloves in a microwavable bowl, add enough water to cover, and microwave on 100% for 1 minute. Drain. If you prefer a sweeter, toastier flavor to your adobo, toss the garlic cloves, still in their papery skins, in a dry skillet and place over medium heat, turning them regularly until they turn soft and blotchy black, about 15 minutes. Let cool and then remove and discard the papery skins.

Toss the garlic in the blender along with the cinnamon, pepper, cumin, oregano, vinegar, and salt and process until a smooth purée forms. If necessary, stir in some water, a splash at a time, until the adobo is the consistency of barbecue sauce. Transfer the adobo to a pint jar, screw on the lid, and store in the refrigerator for up to a couple months.
