What each ingredient does
- Apples
- Soften into tender pieces that form the body of the dish.
- Lemon juice
- Adds acidity that brightens the flavour and balances sweetness.
- Lemon rind
- Contributes aromatic oils that add fragrance to the dish.
The step that matters
Cook gently until the apples are tender. High heat can break the apples down into a mush before they soften evenly. Gentle heat lets the pieces hold their shape while the starches and pectin soften slowly.
