Ingredients
Directions
Prepare the flour
Tie up the flour tightly in a cloth.
Place it in a saucepan of cold water and boil for 4 to 5 hours.
Remove from water and pare away the outer rind.
Serve
When needed, scrape off a sufficient quantity and mix with boiling milk to achieve a gruel-like thickness.

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.

What each ingredient does
- Flour
- Forms the thick body of the gruel as its starch thickens when mixed with hot liquid.
- Milk
- Adds moisture and softens the cooked flour into a smooth, pourable gruel.
The step that matters
Boiling the flour for 4 to 5 hours. The cloth-wrapped flour must stay submerged in boiling water for the full time so the starch cooks through and the outer layer forms a firm crust that can be pared away. Too short a boil leaves the interior raw and pasty.
