Been making this chili for several years. It's excellent! I use fire roasted tomatoes, and Modelo Negra beer. The beer chosen can really alter the flavor. The chili freezes well, if there's any leftovers. I serve it with corn muffins zhuzhed up with sharp cheddar and green chilies. The chili is delicious on baked potatoes or pasta. We think it's the best chili ever.
Too much tomato flavor. Perhaps use only half the tomato paste. The tomato paste should have been put in before the diced tomatoes and browned well. That would likely correct the problem.
