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 ↓
Dried Apple Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the apple 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 greased loaf pans.
Bake at 350°F (175°C) until done.

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 chewy texture and fruity flavour as they soften in the molasses.
- Molasses
- Adds sweetness, dark colour and moisture, and simmering softens the apples in it.
- Shortening
- Adds fat that tenderises the crumb and carries the spices.
- Eggs
- Bind the batter and add structure to the baked crumb.
- Baking soda
- Reacts with the acidic molasses to help the cake rise and darken.
- All-purpose flour
- Forms the gluten structure that gives the cake its body.
The step that matters
Cooling the apple mixture before adding the other ingredients. Adding baking soda and eggs to a hot mixture can cause the eggs to scramble and the leavening to react too early, weakening the rise. Letting it cool first keeps the batter smooth and the cake's rise even.
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.
