In a medium heavy-bottomed pot set over medium heat, add the onions, jalapenos, garlic, butter, oil, salt and pepper. Sweat the vegetables until tender. Add the stock, tomatoes, chili powder, adobo sauce, salt, tomato paste, chipotle powder, garlic powder, onion powder, black pepper, sugar and cumin. Bring to a boil, then reduce the heat and simmer for 20 minutes.
Add the brisket to the chili. In a small bowl, whisk the maseca into 1 cup warm water to make a slurry. Add the slurry to the chili. Simmer for 5 to 10 minutes, stirring often to avoid letting the meat settle on the bottom.
Cut open a bag of chips from the top or side, ladle in some chili over the chips. Repeat for the remaining bags of chips and chili. Top with some Cheddar, red onions, some jalapenos for more heat and maybe even a dollop of sour cream! Mix it up and eat!
Keep the jalapeno seeds for more heat in the chili. Use 2-ounce bags of the corn chips for individual servings or spread the chips in a bowl and pour the chili on top.
