Add onion and garlic and cook until onions are translucent.
Add stock, chili powder, comino, salt, and pepper.
Bring to a simmer and cook for 2-3 hours or until beef is very tender.
In a separate skillet mix flour and oil together to form a roux.

Be careful not to let it burn.
Carefully add roux to stewed beef.
Be very careful because it can splatter.
Bring back to a simmer and thicken, simmer for 5-10 minutes to allow flavors to meld.
