How to Make It
Combine first 5 ingredients in a medium saucepan; bring to a simmer over medium heat. Stir well to dissolve achiote paste. Cover pan, and remove from heat; let stand 30 minutes. Combine stock mixture, 1 can kidney beans, and 1 can small red beans in a blender. Remove center piece of blender lid (to allow steam to escape); secure blender lid on blender. Place a clean towel over opening in blender lid (to avoid splatters). Blend until smooth. Set aside.
Preheat oven to 325°.
Heat a large Dutch oven over high heat. Add 1 1/2 teaspoons oil to pan; swirl to coat. Add half of beef; cook 4 minutes or until very well browned, stirring occasionally. Remove beef from pan. Repeat procedure with remaining 1 1/2 teaspoons oil and beef. Reduce heat to medium-high. Add onion, bell pepper, cumin, sugar, salt, black pepper, and garlic; sauté 4 minutes or until vegetables are tender.
Add beer to pan; cook 5 minutes or until liquid is reduced by half. Add tomatoes; crush well with side of a spoon or tongs. Add beef. Stir in stock mixture, remaining 1 can kidney beans, and remaining 1 can small red beans. Cover loosely to allow steam to escape; bake at 325° for 90 minutes.
