Why it works: Sugar and lemon are a kitchen classic. They rank in the top 18% of all ingredient pairs, and 53,532 recipes mention both. Both carry 2-nonenal, which smells fatty, green. The science ↓
The Improved Method Op Canning Strawberries and Raspberries By Simply Compounding a Syrup
Ingredients
Directions
Prepare the berries
Select perfect berries, preferably large and not too ripe.
Rinse berries in a colander with a little water, lifting them occasionally to drain.
Hull the berries and layer them with ½ pound of granulated sugar in a stone crock.
Cover the crock and let it sit overnight or from 8 A.M. to 4 P.M. in a cool place.
Carefully skim the berries from the syrup and transfer them to another vessel.
Make the syrup
To the syrup, add ½ pound of pulverized rock candy or additional sugar and stir well.
Bring the syrup to a boil, adding a pinch of baking soda to remove impurities.
Skim the syrup clean and add 5 drops of lemon juice to prevent candying.
Boil the syrup for about 20 minutes, stirring only as necessary to prevent burning.

Shared aroma: 2-nonenal (fatty, green).
Sugar and lemon share little aroma chemistry, yet 53,532 recipes mention both: they likely work on texture and structure more than aroma.

What each ingredient does
- Strawberries or raspberries
- Provide the fruit that is preserved and gives the dish its flavor and color.
- Granulated sugar
- Draws juice out of the berries and preserves them in a concentrated syrup.
- Pulverized rock candy or additional sugar
- Adds more sugar to thicken and sweeten the syrup further.
- Lemon juice
- Adds acidity that helps prevent the sugar from crystallizing into candy.
The step that matters
Boil the syrup gently and stir only as needed. Sugar syrup can scorch on the bottom of the pan if overheated or stirred too little, giving a burnt taste. Stirring only as needed limits the sugar crystals that can form on the pan sides, which can trigger graining. Keeping the boil steady and monitoring the pan protects both flavor and texture.
