Best beans in the world
Unlike a thin stovetop soup, this baked bean dish relies on a dense matrix of legumes, cured pork, and concentrated sweeteners that requires careful thermal management. Sweet onion and bacon form the aromatic foundation of the dish, but they must be rendered properly before assembly. Render the chopped bacon and sweat the diced sweet onion over medium heat until the onions achieve a deep caramel color and the bacon fat completely liquefies. This prevents raw pockets of crunchiness in the final bake. Transfer the mixture to a buttered glass or ceramic casserole dish.
High concentrations of brown sugar, ketchup, and dark molasses demand precise oven control to prevent scorching. Set the oven accurately to 350 degrees Fahrenheit. Cube the extra-sharp cheddar cheese uniformly so it melts evenly into the bean mixture rather than separating into oily pools. Drain the canned red kidney beans and pinto beans thoroughly through a colander to remove excess canning liquid, which otherwise thampers the thickening action of the sugars and starches. Reserve the parmesan cheese for the final five minutes of baking so the dairy proteins toast without burning.
