Instructions
Step 1
Using a large chefs knife, slice the the kernels from the corn cobs, reserving the kernels (about 2 cups) and their juices (discard the cobs). Set a few kernels aside for garnish if desired.
Step 2
Transfer the corn kernals to a blender and pulse until coarsely ground. Add 2 cups water, the milk, sugar, and cinnamon or vanilla, and blend on high until very smooth.
Step 3
To a medium pot over medium-low heat, add the corn mixture, bring to a low boil, then stir in the salt. Continue cooking, stirring occasionally, until the atol de elote is slightly thickened, about 15 minutes. Remove from the heat and ladle into heatproof cups or mugs. Garnish with any reserved corn kernels and a bit more cinnamon if desired.
