Why it works: Sugar and egg are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 122,807 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Syrup for Preserves
Ingredients
Directions
Combine sugar, water, and egg white in a large, white, china-lined kettle.
Stir well and bring to a boil over medium heat.
Boil for 5 minutes, ensuring it bubbles and froths.
Remove from heat and let it settle, then skim thoroughly.
If the syrup rises too quickly, add a dash of cold water to control it.
Once skimmed, return to a boil and prepare your fruit.

What each ingredient does
- White sugar
- Forms the bulk of the syrup and sets its sweetness and body once dissolved and boiled.
- Egg white
- Coagulates as it heats, trapping impurities so they rise to the surface for skimming.
The step that matters
Boiling until the syrup froths. Egg white must be heated until it bubbles and froths so it can collect impurities. If the syrup rises too fast, a dash of cold water calms it, preventing boil-over.
