Why it works: Caviar and butter work together. They rank in the top 10% of all ingredient pairs, and cooks put them together in 107 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Sturgeon a LA Ude
Ingredients
Directions
Prepare the fish
Clean and wash the sturgeon.
Place it in a fish kettle with salt and cover with boiling water.
Boil until cooked.
Make the sauce
In a saucepan, boil the elder vinegar until reduced by half.
Add the velouté sauce and caviar to the vinegar and bring to a boil.
Move the sauce to the side of the fire and add butter and beaten egg yolks.
Season with salt and pepper, stirring until thick but do not boil after adding eggs.
Serve
Drain the fish, place it on a hot dish, pour the sauce over it, and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sturgeon
- Is the main protein that is poached and served with the sauce.
- Elder vinegar
- Reduced by boiling to concentrate its sharp acidity for the sauce.
- Velouté sauce
- Forms the thickened base that gives the sauce body.
- Butter
- Adds richness and a smooth, glossy texture to the sauce.
- Egg yolks
- Thicken the sauce through gentle heating and add richness.
- Caviar
- Adds salty, briny flavour and a garnish-like finish to the sauce.
The step that matters
Adding the egg yolks. Egg yolks thicken by setting gently at moderate heat. If the sauce boils after the eggs go in, the yolks can scramble and curdle, leaving the sauce grainy instead of smooth.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
