Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Beef top round steak: Provides the main protein; thin slices across the grain cook quickly and stay tender.
Sweet potatoes: Add starch and body, softening as they cook in the covered skillet.
Sweet green peppers: Add crisp-tender texture and fresh, slightly bitter flavor when sautéed.
Onion: Adds savory sweetness as it softens and browns in the oil.
Curry powder: Provides warm, aromatic spice flavor that blooms when sautéed in oil.

The step that matters

Add water, cover, cook until potato is tender. Covering traps steam so the potato slices cook through evenly; the water must not boil dry before the potato softens, or the vegetables scorch in the spiced oil.
