Sweet almonds
Contribute body and a nutty flavour to the paste.
Loaf sugar
Sweetens the mixture.
Lemon peel
Adds aromatic citrus flavour.

The step that matters

Work the mixture through an earthenware colander. Pressing the mixture through a fine sieve breaks up lumps of almond and yolk, giving the smooth, even texture the dish depends on. Skipping or rushing this step leaves a grainy result.
