Egg and vanilla barely smell alike, yet cooks put them together in 27,347 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Chocolate
Provides the main chocolate flavor and the melted coating over the layers.
Plain fondant
Forms the sweet, creamy layers that give the bar its body.
Fondant lump
Adds more sweet, creamy fondant to the mixture with the melted chocolate.

The step that matters

Let it sit for a day before cutting. Resting lets the fondant and chocolate firm and set together, so the squares hold their shape when cut instead of smearing or crumbling.
