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

What each ingredient does

Hind legs of frogs
The main protein, which becomes tender through slow stewing in the liquid.
Butter
Fat that browns the legs, adding roasted flavour before the stew.
Wine
Acidity and aroma that flavour the stewing liquid and help tenderise the meat.
1 egg yolk
Stirred in at the end to enrich and thicken the sauce slightly.

The step that matters

Stirring in the egg yolk. Egg yolk thickens when heated gently but can curdle if the stew is boiling hot. Beat it well and stir it in off the heat or with the pot just below a simmer for a smooth, lightly thickened sauce.

Swap the onion

How well each one fits the dish's main ingredients (butter, parsley, thyme, pepper, wine, egg):
