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 ↓

What each ingredient does
- White flour
- Forms the dried lump that is grated and used to thicken the milk.
- Milk
- Forms the liquid base of the gruel, which the flour thickens.
The step that matters
Thicken the milk with the grated flour mixed in cold water. Flour must be mixed into cold water before it goes into hot milk; otherwise the starch clumps instead of dispersing evenly, leaving lumps in the gruel.
