Place dried corn in a pot. Add boiling water to cover the corn and a generous spoonful of baking soda. This will give the corn a yellow color. Optional: use hickory ash instead.
Let the corn become plump and soft, but not falling apart.
Transfer the corn to the sink and rinse with cold water.
Rub the corn between your hands to remove the hull.
Rinse the corn three times to ensure that it’s clean.
In a large bowl or pot, soak the kidney beans in water until they are fully rehydrated.
In a separate pot, boil the soaked kidney beans with cubed lean salt pork (not the heavily salted variety). Do not add salt as this dish gets its salt from the meat.
Add the hominy to the pot of beans and pork. Simmer 30 min to allow flavors to meld.
