In a saucepan, add the Cascavel chili, ancho chili, tomatoes, and garlic cloves. Cover with water and cook over medium-high heat for about 10 minutes, or until the peppers are tender and the skins of the tomatoes crack.
Strain the water and place the contents in a blender. Blend on high until smooth. Strain the contents with a colander and set aside.
Add the deer meat to a large bowl. Toss in the flour and Kent Rollins’ Mesquite Seasoning, until well coated.
Add the oil to a large cast iron skillet or Dutch oven and heat over medium-high heat. Cook for about 3 to 4 minutes, or until the meat begins to brown. Stir in the onion and cook for about 5 minutes, stirring occasionally.
Stir in the tomato paste and mix well. Cook for about 2 minutes.
To a medium stockpot, add the blended chili mixture and deer meat. Stir in the beef broth, cocoa powder, cinnamon, beer, kidney beans, and Kent Rollins’ Chili Seasoning. Place over medium-low heat and cook over a simmer for 45 to 60 minutes, or until the meat is tender, stirring occasionally.
