Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ingredients
Directions
The book gives no oven temperature. The 100°F in the steps was added when the recipe was transcribed, as a starting point.
Prepare the steak
Remove any fat from the steak and wipe it with a wet cloth.
Heat a pan over high heat and quickly sear the steak to keep the blood in.
Before removing the steak from the pan, smear it with a little butter and a dash of coarse sea salt.
Extract the blood
Cut the steak into small pieces that fit into a lemon squeezer.
Press out the blood into a preheated small cup and serve immediately.
Make the milk whey
Warm the milk to just above blood heat (about 100°F or 38°C).
Pour the sherry wine into the warm milk.
Let the mixture sit until the albumen coagulates, then strain without squeezing the curd.
For quick whey, heat the milk to boiling before adding the wine.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lean round steak
- Provides the blood-rich meat that is pressed to yield the extract.
- Milk
- Serves as the base that the sherry wine curdles into whey.
- Sherry wine
- Acidity causes the milk proteins to coagulate and separate into curd and whey.
The step that matters
Searing the steak quickly over high heat. A brief, hot sear firms the outside of the meat so less blood escapes before pressing. Overcooking it would cook the meat through and reduce the blood you can extract.
“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.
