Place the corn in a deep pot, and add enough water to cover it plus a couple of inches. Boil corn until it is very soft. For this I highly recommend you use a pressure cooker (it will take 45 minutes in a pressure cooker, 2-3 hours or more in a regular pot). If you use a regular pot, keep an eye on it, and add water as it becomes necessary to keep the same level of liquid.
How to make chacá
In a thick bottomed pot add corn, rice, 1 ½ quart of water (better if it is the water in which you boiled the corn, add fresh water if needed), milk, cinnamon, and cloves.
Cook over low heat until the liquids reduce to half and the rice is cooked through, stir often to prevent it from sticking and scorching, especially if you have added rice. Once cooked through, add the butter, raisins, salt, and sugar to taste.
Chill before serving.
Notes
This is the cracked corn [Amazon affiliate link] that would work for this dish.The consistency of this dish is a matter of taste. While purists will aim for a thick, creamy one, my taste is for a less-thick (more like soup) one. My solution is just to add more milk and adjust sugar once it's chilled.Rice is optional. This is how my mother made it, but it is not the most popular version.
