Oatmeal Cracknels

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the dough

  1. Mix oatmeal and milk.

  2. Let the mixture stand for 5 hours in a cold place to swell.

  3. Sift together Graham flour, salt, and baking powder.

  4. Add the dry ingredients to the oatmeal mixture. Mix into a smooth dough.

Shape the crackers

  1. Flour a board with cornmeal.

  2. Turn out the dough.

  3. Roll it to ½ inch thick.

  4. Cut out shapes with a cutter.

  5. Lay them on greased baking tins.

  6. Brush the tops with milk.

Bake

  1. Bake for 10 minutes in a moderate oven at 350°F (175°C).

The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

    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

Fine oatmeal
Forms the bulk of the dough and gives the crackers their hearty, grainy texture.
Graham flour
Adds structure and a nutty, wholesome flavor to the dough.
Baking powder
Releases gas that lightens the dough and helps the crackers rise slightly.
Milk
Hydrates the oatmeal so the dough binds, and browns the tops when brushed on.

The step that matters

Let the oatmeal and milk stand. Standing for hours in a cold place lets the oats absorb liquid and swell, which softens them and helps the dough hold together when rolled.
