Preserving Fruit in Bottles
Ingredients
Directions
The book says “a very slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Fill and cork
Fill bottles with fruit, leaving space at the top.
Cork the bottles loosely with new soft corks.
Bake
Place bottles in a very slow oven at 300°F (150°C) for four to five hours.
Remove bottles when the fruit begins to shrink inside.
Seal and store
Tighten the corks before the bottles cool.
Store bottles upside down in a rack or basket.

What each ingredient does
- Fruit
- Is the food being preserved, softening and shrinking slowly in the low oven heat.
- New soft corks
- Loosely placed corks let steam escape during baking, then are tightened to seal the bottles.
The step that matters
Tighten the corks before the bottles cool. As a sealed bottle cools, the air inside contracts and creates a partial vacuum that pulls the cork tighter. Tightening the corks while the bottles are still warm ensures a firm seal forms during cooling.
