Why it works: Raspberry and sugar are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 3,101 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Raspberry Syrup
Ingredients
Directions
The book gives no oven temperature. The 150°F (65°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Press the juice from the raspberries using a combination press.
Make the syrup
In a pot, gently heat the raspberry juice and dissolve the sugar, ensuring the temperature does not exceed 150°F (65°C).
Mix the acetic acid with water and add to each gallon of juice before bottling.
Bottle
Bottle the syrup while warm and cork it for future use.

What each ingredient does
- Raspberry juice
- Provides the main raspberry flavor and the liquid base of the syrup.
- Granulated sugar
- Sweetens the syrup and helps preserve it by binding water.
- Acetic acid
- Adds tartness that balances the sweetness and aids preservation.
The step that matters
Keep the temperature at or below 150°F (65°C) while dissolving the sugar. Gentle heat dissolves sugar without cooking off the fresh raspberry flavor or breaking down its aromatic compounds. Overheating can darken the syrup and dull its taste.
