Ingredients
Directions
Prepare
Wipe the rhubarb dry.
Peel the rhubarb if it is not young.
Cook
Combine the rhubarb, sugar, chopped almonds, and lemon peel in a pot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rhubarb
- Forms the bulk of the preserve and supplies the tart flavour the sugar balances.
- Sugar
- Sweetens the fruit and, as it concentrates, helps preserve and set the mixture.
- Blanched bitter almonds
- Add a nutty, bitter aroma and some texture to the preserve.
- Lemon peel
- Adds bright citrus aroma that lifts the sweet and tart flavours.
The step that matters
Boiling until the mixture sets firm. Rhubarb is low in natural setting agents, so the mixture must boil long enough to thicken as water evaporates and sugar concentrates. Stopping early leaves it runny, while overcooking can make it dense and overly sticky.
