Why it works: Ginger and sugar are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 14,054 recipes. Both carry 1-penten-3-one, which smells fish, pungent. The science ↓
To Preserve Ginger
Ingredients
Directions
Prepare the ginger
Pare the ginger with a sharp knife.
Place the ginger in a pan of cold water to keep it white.
Boil the ginger until tender, changing the water three times, and placing it in cold water each time.
Drain the ginger and place it in an earthen pan.
Syrup and soak
Cover the ginger with enough cold sugar to fully submerge it and let it stand for two days.
Pour the syrup from the ginger into the remaining sugar and boil it.
When the syrup is cold, pour it back over the ginger and let it sit for at least three days.
Remove the syrup from the ginger, boil it, and pour it hot over the ginger.
Repeat this process until the sugar has fully absorbed into the ginger, skimming off any scum that rises.

Shared aroma: 1-penten-3-one (fish, pungent).
Ginger and sugar barely smell alike, yet cooks put them together in 14,054 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green ginger
- Forms the preserved pieces, which become tender and soak up the sugar syrup.
- Refined sugar
- Preserves the ginger and gives it sweetness as the syrup penetrates the pieces.
The step that matters
Repeating the syrup pour until the sugar is fully absorbed. Sugar must replace the water in the ginger gradually through repeated boiling and soaking. Pouring the syrup back too early or stopping before absorption is complete leaves the ginger wet and poorly preserved.
