Why it works: Butter and milk match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and 81,222 recipes mention both. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
The recipe
Ingredients
Contains: egg, milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Bake the potatoes until done, then remove them immediately.
Slice cold mush and place on slightly buttered pans.
Warm the pans in the oven.
Make the gruel
Mix equal parts of cornmeal or Graham flour with oatmeal.
Stir 1 cup of this mixture into 2 quarts of boiling water and boil for 20 minutes.
Add 1 quart of milk to the mixture and pour into a pitcher.
Serve
Serve puddings or cracked wheat cold or slightly warmed with sugar and hot milk or stewed berries.
For a thicker gruel, adjust the amount of mixture used.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cornmeal
- Its starch thickens as it cooks in boiling water, giving the gruel body.
- Graham flour
- Its starch thickens the gruel and adds a mild, nutty flavor.
- Oatmeal
- Its starch thickens the gruel and adds a soft, porridge-like texture.
- Milk
- Adds creaminess and softens the gruel's flavor after cooking.
- Butter
- Adds fat that keeps the slices from sticking to the buttered pans.
The step that matters
Stirring the flour mixture into boiling water. Starch granules clump if dropped in unevenly. Stirring the mixture in while the water boils disperses the grains so they thicken smoothly rather than forming lumps.

Fit is the average pairing score against flour, butter, potato, cream, egg, milk, sugar. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
