Why it works: Rhubarb and nutmeg match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 177 recipes. Both carry acetic acid, which smells sour, vinegar. The science ↓
Rhubarb Pie
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the rhubarb
Cut the rhubarb stalks where the leaves begin and remove the outer skin.
Cut the stalks into pieces half an inch long.
Assemble the pie
Line a pie dish with rolled pie crust thicker than a dollar coin.
Add a layer of rhubarb nearly an inch deep.
In a bowl, mix the rhubarb with sugar, salt, nutmeg, and a little flour.
Strew the mixture over the rhubarb in the pie dish.
Cover with a rich pie crust.
Cut a slit in the center.
Trim the edges.
Bake
Bake in a 400°F (200°C) oven until the pie loosens from the dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rhubarb
- Provides the tart flavour and the bulk of the filling.
- Sugar
- Sweetens the filling and balances the rhubarb's sourness.
- Flour
- Thickens the juices released by the rhubarb so the filling sets.
The step that matters
Adding the flour and sugar mixture. Rhubarb releases a lot of liquid as it bakes. The flour must be evenly mixed through the fruit so it can thicken those juices; otherwise the filling can run and leave a watery, underset pie.
Swap the nutmeg
How well each one fits the dish's main ingredients (rhubarb, sugar, flour):
- Cinnamonfits better
- Jalapenofits about as well
- Nutmegthe original
- Capersfits about as well
Fit is the average pairing score against rhubarb, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
