Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Provide the bulk and fruity flavor of the puree, which also carries natural pectin that helps it set.
- Sugar
- Adds sweetness and balances the tartness of the apples and lemon.
- Butter
- Adds richness and a smooth, velvety mouthfeel to the puree.
- Arrowroot
- Thickens the puree when heated, giving it a glossy, set texture.
- Lemon
- Adds acidity that brightens the flavor of the apples.
The step that matters
Simmer until thick. Arrowroot thickens as it heats and gels in the hot puree, but it loses thickening power if it is overcooked or held at a rolling boil for too long. Stop once the mixture coats a spoon, then let it cool, since it thickens further as it sets.
Swap the apple
How well each one fits the dish's main ingredients (lemon, cinnamon, sugar, butter, arrowroot):
