Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Matsoni
- Forms the soup's base, giving it a sour, tangy flavour and creamy body.
- Wheat flour
- Thickens the mixture as it heats, giving it body and stopping it from being watery.
- Eggs
- Add richness and help thicken the soup as they gently set in the hot liquid.
- Butter
- Adds fat and flavour, and helps the onions soften and brown gently.
- Onions
- Turn sweet and aromatic when stewed slowly in butter, balancing the sourness of the yoghurt.
The step that matters
Pouring the egg without boiling. Pour the beaten egg slowly while stirring constantly, then take the pan off the heat before it boils. Stirring spreads the egg evenly, and avoiding a boil stops it from scrambling or curdling in the hot yoghurt mixture.
