Why it works: Tomato and beans match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 2,713 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Slow Cooker Mexican Beef Stew
Ingredients
Directions
Cook the beef
Mix beef, tomatoes, frozen onions and chili powder in a 3½- to 4-quart slow cooker.
Cover and cook on low heat setting 9 to 11 hours or until beef is tender.
Finish the stew

Stir in black beans and corn.
Cover and cook on high heat setting 15 to 30 minutes or until thickened.
Notes
Note: This recipe was tested in slow cookers with heating elements in the side and bottom of the cooker, not in cookers that stand only on a heated base.
For slow cookers with just a heated base, follow the manufacturer's directions for layering ingredients and choosing a temperature.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef stew meat
- Long, slow cooking breaks down connective tissue, making the meat tender and the broth richer.
- Whole tomatoes
- Provide the liquid base and bright acidity that carry the chili flavors through the stew.
- Frozen onions
- Soften and turn sweet as they cook, adding depth to the sauce.
- Black beans
- Hold their shape in the stew and add body and earthy substance.
- Mexicorn with red and green peppers
- Adds pops of sweetness and pepper aroma to the finished stew.
The step that matters
Cook on low until the beef is fully tender. Stew meat is tough until its connective tissue slowly converts to gelatin over long, gentle heat. Stopping early leaves the beef chewy, so check tenderness before moving on.
