Why it works: Orange and sugar are a kitchen classic. They rank in the top 20% of all ingredient pairs, and cooks put them together in 19,212 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Preserved Orange Peel
Ingredients
Directions
Boil the Seville orange peel in plenty of water until tender but not mushy.
Transfer the boiled peel to cold water and remove the pulp using your thumb.
Soak the peel in fresh water, changing it daily for three days.
Drain the peel on a coarse sieve for one day.
Pack the peel in a tub or jar, placing them one into another.
Pour boiling hot clarified sugar over the peel to cover them completely.
The next day, drain the syrup and boil it for about 15 minutes.
Pour the hot syrup over the peel and repeat this process every other day for three to four times until the syrup is thick.
Ensure there is always enough syrup to cover the peel.
Let the peel remain in syrup for at least three months before candying.
