  2. Add the almonds to the syrup and boil for one minute.

What each ingredient does

Sweet almonds
Provide the main nutty flavour and body of the syrup.
Bitter almonds
Add a sharper, more aromatic almond note that balances the sweetness.
Clarified sugar
Sweetens the syrup and gives it body and preservation.
Orange-flower water
Adds a floral, aromatic fragrance to the almonds.
Rose water
Adds a delicate floral aroma that complements the almonds.

The step that matters

Boiling the sugar to the crack stage. Sugar must be boiled until it cracks when dipped in cold water so the syrup reaches the right concentration. Too little cooking leaves it thin and more prone to spoiling, while overcooking makes it hard and sticky once cooled.
