Corn and Graham Johnny Cake

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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

Preheat oven to 350°F (175°C).
In a large bowl, mix cornmeal, melted butter, graham flour, baking soda, all-purpose flour, and salt.
In another bowl, beat eggs and combine with sour milk (or molasses or sour cream).

Mix and bake

Pour wet ingredients into dry ingredients and mix until just combined.
Pour batter into a greased baking dish and bake for about 30‑40 minutes, or until a toothpick comes out clean.

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

What each ingredient does

Cornmeal: Provides the main body and the coarse, gritty texture typical of johnny cakes.
Graham flour: Adds a nutty, slightly coarse texture and a deeper wheat flavour to the batter.
All-purpose flour: Gives structure so the batter holds together after baking.
Baking soda: Reacts with the acidic sour milk, molasses or sour cream to lift and lighten the cake.
Eggs: Bind the batter and add structure and richness as they set in the oven.
Sour milk: Its acidity activates the baking soda and adds tang and moisture.

The step that matters

Mix wet and dry ingredients until just combined. Baking soda starts reacting as soon as it meets the acidic liquid. Overmixing develops gluten and knocks out the gas bubbles, leaving a dense, tough cake, so stop once no dry streaks remain.
