Black Bean and Sirloin Chili

I've had this recipe for a long time and use it to create other chilis from. It's a favorite in our house.

Black Bean and Sirloin Chili

1/3 cup olive oil
2 lb. sirloin, cut into 1/2 inch cubes
1 yellow onion, chopped
4 cloves garlic, minced
4 jalapenos, seeded and chopped fine
1/3 cup Masa Harina
1/3 cup regular chili powder
1 tsp. ancho chili powder
1/2 tsp. ground cumin
2 ( 14.5 oz.) cans chicken broth
2 cups cooked black beans (rinsed and drained if using canned)

Brown sirloin, in batches, in a heavy pot with olive oil, transferring it to a plate with a slotted spoon as it is browned. In remaining fat, cook onion, garlic and peppers over moderate heat, stirring until onion is softened. Add Masa, chili powders and cumin, stir and cook for 5 minutes. Add broth and sirloin and simmer, uncovered, stirring occasionally, for 45 minutes. Stir in beans and simmer for 15 minutes. Add salt to taste. Serve.
