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 ↓
Marmalade
Ingredients
Directions
Prepare the fruit
Grate one-third of the oranges and pour boiling water over the gratings.
Cover until ready to cook.
Cut the oranges into quarters and remove the skins.
Scrape the pulp from the inner skins and wash the seeds and refuse in 2 pints of water.
Strain the washed mixture into the marmalade.
Boil the skins in cold water for about 4 hours.
Cut the boiled skins into straw-like pieces and add to the mixture.
Cook and strain
Strain the mixture, keeping the gratings separate, and add the water to the marmalade.
Boil everything together for about 40 minutes, adding boiling water to the skins after an hour.
