Why it works: Syrup and sugar match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 5,842 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓

Crumb Pie

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare the base

  1. Roll the pie dough into a thin sheet and line a pie dish.

  2. Spread syrup over the dough.

Make the crumb

  1. In a bowl, rub together the butter, sugar, and flour until combined.

Assemble and bake

  1. Fill the pie dish with the mixture and grate nutmeg on top.

  2. Bake in a 400°F (200°C) oven until golden.

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

What each ingredient does

Pie dough
Forms a crisp base that holds the syrup and crumb filling.
Syrup
Adds sweetness and a sticky, moist layer beneath the crumb.
Butter
Adds fat and richness, and helps bind the flour and sugar into crumbs.
Flour
Gives the crumb its body and structure as it bakes.
Sugar
Adds sweetness and helps the topping brown as it bakes.

The step that matters

Rubbing the butter into the flour and sugar. The butter should be worked in until the mixture is evenly crumbly with no large lumps. Unevenly distributed butter melts unevenly in the oven, and overworking the mixture can make the topping dense and pasty instead of loose and crumbly.

Swap the nutmeg

How well each one fits the dish's main ingredients (syrup, sugar, flour, butter):

  1. Cinnamonfits better
  2. Jalapenofits about as well
  3. Nutmegthe original
  4. Gingerfits less well

Fit is the average pairing score against syrup, sugar, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
