Why it works: Butter and rum are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 1,007 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Gruel
Ingredients
Directions
Prepare
Boil 1 pint of water in a stew-pan.
In a basin, mix 2 teaspoons of patent groats with 2 tablespoons of cold water to form a smooth paste.
Cook
Once the water is boiling, pour in the groat mixture and stir well with a wooden spoon.
Cook for 10 minutes, ensuring it remains smooth and lump-free.
Pour the gruel into a basin.
Finish and serve
If serving cold, stir in 1 oz. of fresh butter and sweeten to taste.
Add ⅓ cup of rum if desired, unless the patient is feverish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Patent groats
- Thicken the water into a smooth, porridge-like gruel as they cook.
- Fresh butter
- Adds richness and a silky mouthfeel to the finished gruel.
- Rum
- Adds aroma and warmth to the gruel when included.
The step that matters
Mixing the groats into a paste before adding them to the water. Dry groats dropped straight into hot water clump, leaving lumps that do not smooth out. Blending them with cold water first lets the starch disperse evenly so the gruel thickens evenly as it cooks.
