Rhubarb Jam
Ingredients
Directions
Combine rhubarb, sugar, lemon rind, almonds, and ginger in a pot.
Cook over medium heat until it boils, then stir for 45 minutes.
If the rhubarb is very juicy, boil a little longer.
Pour the jam into pots and let it cool.

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 flavour that the jam is built around.
- Sugar
- Sweetens the jam and, as it cooks down, helps it thicken and set.
- Lemon rind
- Adds bright aromatic oils that lift the flavour of the rhubarb.
- Almonds
- Contribute a subtle nutty aroma to the jam.
The step that matters
Stirring and boiling until the jam is done. Rhubarb releases a lot of water, and the jam only thickens once enough of that water evaporates with the sugar concentrated. Undercooking leaves it runny, while stirring keeps the sugar from scorching on the bottom of the pot.
Swap the ginger
The recipe marks ginger as optional. How well each one fits the dish's main ingredients (rhubarb, sugar, lemon, almond):
- Cinnamonfits better
- Nutmegfits better
- Capersfits about as well
- Gingerthe original
Fit is the average pairing score against rhubarb, sugar, lemon, almond. Candidates are from the same food group and used in at least 100 recipes.
