Oatmeal Water

Ingredients

Directions

Make the oatmeal water

  1. In a pot, combine 1 quart of water with 3 oz of coarse oatmeal.

  2. Simmer gently on the stove for about 2 hours.

  3. Strain the mixture through a fine sieve or gravy strainer, pressing well to extract all the goodness.

Finish and serve

  1. If the mixture is thick, thin it down with additional water or hot milk, using half oatmeal water and half milk for a good mixture.

  2. Add lemon juice and sweetener to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Coarse oatmeal
Releases starch and body into the water as it simmers, giving the drink its thickness.
Water
Acts as the cooking liquid that extracts oat solids and soluble starch during simmering.
Hot milk
Adds richness and a softer, creamier texture when used to thin the mixture.

The step that matters

Simmer gently. A gentle simmer extracts starch and flavour from the oats slowly without scorching the bottom of the pot or boiling off too much water, keeping the liquid smooth.

Swap the lemon
