Gooseberries
Ingredients
Directions
Prepare the alum bath
Dissolve the roche alum in a large pan of boiling hard water.
Place a few gooseberries in a hair sieve.
Hold the gooseberries in the water until they turn white.
Remove the sieve.
Spread the gooseberries between two cloths.
Repeat the process with more gooseberries until all are done.
Transfer the water into a glazed pot.
Let the water sit until the next day.
Bottle and store
Place the gooseberries into wide-mouthed bottles, discarding any cracked ones.
Pour the clear water from the pot into the bottles.
Cork the bottles loosely.
Let the bottles stand for a fortnight.
Check if the gooseberries rise to the corks.
If they do, uncork the bottles for two or three days.
Cork them tightly again.

- Gooseberries
- The fruit being preserved; its skins are what the alum firms and holds together.
The step that matters
Holding the gooseberries in the alum water until they turn white. Alum works by firming the fruit's pectin and cell walls. Holding the fruit in the solution for too short a time leaves it soft, while leaving it too long can over-harden it, so watch for the white colour change.
