Why it works: Clove and cinnamon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,189 recipes. Both carry ethyl cinnamate, which smells sweet, balsamic. The science ↓
Spiced Rhubarb
Ingredients
Directions
Prepare the rhubarb
Sprinkle sliced rhubarb with 2 pounds of sugar and let it stand overnight.
In the morning, drain the syrup into a preserve kettle.
Make the syrup
Add 3 pounds of sugar and 1 cup of vinegar to the syrup and heat over the fire.
Tie cloves, ginger root, and cinnamon in a muslin bag and add to the syrup.
Boil the syrup until it thickens, then skim out the spice bag.
Cook and store
Add the rhubarb to the syrup and cook until clear.
Carefully transfer the rhubarb to jars for storage.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rhubarb
- Provides the main body and tart flavor of the preserve.
- Sugar
- Draws moisture out of the rhubarb and thickens the syrup, while preserving the fruit.
- Vinegar
- Adds acidity that brightens the sweet syrup and helps balance its sweetness.
- Whole cloves
- Infuse warm, aromatic spice into the syrup.
The step that matters
Boil the syrup until it thickens. Boiling concentrates the sugar syrup so it sets properly and keeps the rhubarb preserved. Stopping too early leaves a thin syrup that spoils more readily, while overcooking can make the syrup too stiff.
Swap the rhubarb
How well each one fits the dish's main ingredients (sugar, syrup, vinegar, clove, ginger, cinnamon):
