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

What each ingredient does

Tilapia fish: Forms the main body of the balls, providing protein structure that holds the shape when flaked and bound.
Raw peanuts: Add nutty flavour and body, and toasting them first deepens their aroma before grinding.
Grated onions: Add moisture and savoury flavour, and their juices help bind the mixture.
Chicken broth: Adds moisture so the mixture can be shaped and holds the balls together.
Lemon juice: Adds acidity that brightens the fish flavour and tenderises it while it seasons.

The step that matters

Adding the broth. Too little broth leaves the mixture crumbly and unable to hold its shape, while too much makes it soft and wet, so the balls may break apart in the hot oil. Add it gradually until the mixture just holds together.
