Why it works: Milk and flour are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Gruel of Kernel Flour or Middlings
Ingredients
Directions
Make the gruel
Put a pint of boiling water in a saucepan over the fire.
Mix two heaping teaspoonfuls of the flour with a little cold water and stir into the boiling water.
Let it boil for twenty minutes.
Add a little cream to it and salt.
Make the yeast milk
Dissolve a third of a cake of compressed yeast in a little tepid water.
Take a quart of milk, fresh from the cow or warmed to blood heat, and add to it a tablespoonful of sugar and the dissolved yeast.
Put the mixture immediately in beer bottles with patent stoppers, filling to the neck.
Let them stand for twelve hours at a temperature of 68 or 70 degrees.
Stand the bottles upside down on ice until wanted.
Nutrition, whole recipe (rough)
Counts 4 of 5 ingredients. The other 1 aren't in our nutrition table and add nothing above, so the real totals are higher.
What these numbers assume: 4 portions
| Ingredient | Portion assumed | kcal |
|---|---|---|
| Flour | 1 cup (125g) all-purpose | 455 |
| Milk | 1 cup (244ml) whole | 149 |
| Sugar | 1 tbsp (12.5g) granulated | 49 |
| Salt | 1 tsp (6g) | 0 |
| Water | not in our table | 0 |

Milk and flour barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base and supplies the sugars and proteins the yeast works on.
- Compressed yeast (in the method)
- Ferments the sugar in the milk, producing carbonation and a lightly sour, lively flavour.
- Sugar
- Feeds the yeast during the standing period and adds sweetness.
- Flour
- Cooked into the boiled water, it thickens the gruel and gives it body.
The step that matters
Filling the bottles to the neck with the yeast milk and standing them at 68 to 70 degrees. Yeast needs a steady warm temperature to ferment, and sealed bottles trap the carbon dioxide produced, so the mixture carbonates. Overfilling leaves no room for gas and can burst the bottles, while cold slows fermentation too much.
“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.
