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 Tart
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.
Make the filling
In a pot, combine rhubarb, water, brown sugar, salt, and grated nutmeg.
Stew the mixture gently until the rhubarb is soft.
Beat the mixture until smooth.
Assemble the tart
Line small tartlet pans with pastry.
Spread a layer of the stewed fruit about ¼ inch deep.
Roll out additional pastry.
Brush the pastry with beaten egg yolk mixed with milk.
Cut the pastry into ¼ inch wide strips.
Lay the strips across the tart.
Add a band of pastry around the edge.
Trim the edges.
Bake
Bake in a preheated oven at 400°F (200°C) until the pastry loosens from the dish, about 30 minutes or more.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rhubarb
- Provides the tart filling's main body and sharp, tangy flavor once stewed.
- Brown sugar
- Sweetens the stewed rhubarb and adds a deeper, caramel-like flavor.
- Pastry
- Forms the tart shell and lattice top that hold the filling in place.
- Egg yolk
- Brushed over the pastry to promote browning and a glossy finish.
The step that matters
Stewing the rhubarb gently. Rhubarb breaks down into a smooth filling only when cooked slowly. High heat can scorch the sugar and leave pieces tough or uneven, so the mixture should be stirred and kept at a gentle simmer until soft.
Swap the rhubarb
How well each one fits the dish's main ingredients (sugar, nutmeg, egg, milk):
- Cinnamonfits better
- Allspicefits better
- Clovefits better
- Rhubarbthe original
Fit is the average pairing score against sugar, nutmeg, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
