Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Whey Gruel for Two Persons
Ingredients
Directions
Prepare
Wash the sago several times with cold and warm water until clear.
Soak the sago in ½ cup of cold or warm water for several hours or overnight.
Cook
Bring 2 cups of whey to a boil with the peeling of ½ lemon or a piece of cinnamon bark.
Stir in the soaked sago and let it boil for 20 minutes.
Add ¼ teaspoon of coarse sea salt.
Finish and serve
Remove from heat and stir in 1 teaspoon of butter, the diluted egg yolk, and a few drops of lemon juice, or add 3 ounces of hot cream instead.
Mix well, pour into soup plates, and serve with soda crackers, zwieback, or ½ raw red Oregon apple.
Add 1 tablespoon of sugar if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sago
- Swells and thickens the whey into a soft, gruel-like porridge as it cooks.
- Whey
- Serves as the cooking liquid, giving the gruel its mild, tangy flavor.
- Butter
- Adds richness and a smooth, silky mouthfeel to the finished gruel.
- Egg yolk
- Enriches the gruel and thickens it slightly for a creamier texture.
The step that matters
Stirring in the egg yolk off the heat. Egg yolk sets at around 65°C and can scramble if it meets boiling liquid. Removing the pot from heat first and stirring the diluted yolk in gently keeps the gruel smooth and creamy.
Swap the lemon
The recipe marks lemon as optional. How well each one fits the dish's main ingredients (whey, butter, egg, cream, apple, sugar):
