Why it works: Egg and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 106,462 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Apple 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.
Prepare the filling
Chop the soaked dried apples and simmer them in molasses for 30 minutes.
Let the mixture cool, then add shortening, eggs, baking soda, flour, and spices. Mix until well combined.
Bake
Pour the batter into a greased baking pan.
Bake in a preheated oven at 350°F (175°C) until a toothpick comes out clean.

Egg and flour barely smell alike, yet cooks put them together in 106,462 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
- Dried apples
- Provide fruit pieces and moisture that keep the cake tender and flavorful.
- Molasses
- Adds dark sweetness and moisture, and softens the dried apples as they simmer.
- Shortening
- Adds fat that tenderizes the crumb and carries flavor.
- Eggs
- Bind the batter and add structure as they set during baking.
- Baking soda
- Reacts with the acidic molasses to produce gas that helps the cake rise.
- Flour
- Forms the main structure of the cake as its proteins set in the oven.
The step that matters
Let the apple mixture cool before adding the other ingredients. Adding eggs and baking soda to a hot molasses mixture can cook the eggs unevenly and cause the baking soda to react too early, weakening the rise.
Swap the apple
How well each one fits the dish's main ingredients (molasses, egg, flour):

- Figfits better
- Applethe original
Fit is the average pairing score against molasses, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
