To Preserve Ginger
Ingredients
Directions
Prepare the ginger
Pare the ginger root with a sharp knife.
Throw the paring ginger into a pan of cold water.
Boil the ginger until tender, changing the water three times. Each time, transfer the ginger to cold water to remove excess heat.
When tender, place ginger in cold water again and let it lie for an hour or more to make it crisp.
Make the syrup
Clarify eight pounds of double-refined loaf-sugar for each six pounds of ginger.
Break up the sugar, put it into a preserving kettle, and melt it in spring or pump water, with beaten whites of four eggs and half a pint water per pound of sugar.
Boil the syrup and skim it well.
Let the syrup stand until it is cold.
Soak and boil
Drain the ginger and pour the syrup over it, cover, and do not disturb for two days.
After two days, pour the syrup from the ginger, boil it again.
When the syrup is cold, pour it again over the ginger and let it stand at least three days.
Boil the syrup again and pour it hot over the ginger.
Repeat the last three steps until the syrup has thoroughly penetrated the ginger and becomes very thick and rich.
Jar and finish
Put the preserved ginger and syrup into jars and cover them closely.
Add lemon juice at the close of the last boiling to improve the result.
Nutrition, whole recipe (rough)
Counts 3 of 4 ingredients. The other 1 aren't in our nutrition table and add nothing above, so the real totals are higher.
What these numbers assume: 3 portions
| Ingredient | Portion assumed | kcal |
|---|---|---|
| Egg | 1 large egg (50g) | 78 |
| Sugar | 1 tbsp (12.5g) granulated | 49 |
| Ginger | 1 tsp grated fresh (2g) | 2 |
| Water | not in our table | 0 |

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
- Ginger root
- Provides the main body and spicy flavour, becoming crisp and tender through repeated boiling and cooling.
- Loaf sugar
- Forms the thick, sweet syrup that preserves the ginger and penetrates it over time.
- Eggs
- Whites are beaten into the syrup so that they collect impurities, which are skimmed off, clarifying it.
- Lemon juice (in the method)
- Adds acidity that brightens the sweetness and balances the rich syrup.
The step that matters
Repeated boiling and resting of the syrup. Syrup must be reboiled and cooled several times so that sugar concentration rises gradually and penetrates the ginger without crystallising or leaving it tough. Rushing this stage leaves the ginger underpreserved and the syrup thin.
Swap the ginger
How well each one fits the dish's main ingredients (sugar, egg):
- Cinnamonfits better
- Nutmegfits better
- Gingerthe original
- Capersfits less well
Fit is the average pairing score against sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
