Why it works: Barley and flour work together. They rank in the top 13% of all ingredient pairs, and cooks put them together in 582 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Patent Barley Gruel
Ingredients
Directions
In a bowl, mix the Patent Barley flour and salt with cold water to form a smooth paste, thick as cream.
Add the boiling water (or milk) to the paste and stir well.
Transfer the mixture to an enamelled saucepan and simmer for 10 minutes, stirring continuously with a wooden or silver spoon.
Add sugar or spirit to taste, if desired.

What each ingredient does
- Patent barley flour
- Thickens the liquid as its starch swells with heat, giving the gruel its body.
The step that matters
Simmer while stirring continuously. Barley starch can settle and scorch on the base of the pan, and constant stirring keeps it dispersed and smooth while it thickens as it simmers.
