Why it works: Flour and milk 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 ↓

Ingredients
Directions
Make the porridge
Make a thick gruel from the farinaceous article.
While still boiling hot, mix the gruel with an equal quantity of cold milk.

Shared aroma: isobutyraldehyde (malty, green).
Flour and milk 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
- Farinaceous article
- Provides starch that thickens the gruel into a porridge body.
- Cold milk
- Adds moisture and dairy richness, and cools the hot gruel.
- Liquor pancreaticus
- Pancreatic enzymes that partly break down proteins and starches, making the porridge easier to digest.
- Bicarbonate of soda
- Raises the mixture's alkalinity, helping the pancreatic enzymes work.
The step that matters
Adding the pancreatic liquor to the mixture. Enzymes are denatured by high heat, so the liquor must be added only after the gruel has cooled with the milk. Adding it to boiling porridge would stop it working. The mixture should also be kept warm, not hot, so the enzymes stay active.
