Strawberry Preserves
Ingredients
Directions
Prepare
Drain the strawberries well and weigh them.
Add an equal weight of sugar to the strawberries.
Add cream of tartar to the sugar, mixing well.
Sprinkle the sugar mixture over the strawberries and shake gently.
Cook and set
Place the mixture over low heat until the juice starts, then cook on brisk heat for 20 minutes.
Turn the mixture onto shallow platters and let it stand overnight or until the juice forms a thin jelly.
While it stands, gently turn the berries with a knife two or three times.
Pack
When ready, pack into jars while cold and seal with paraffin.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Strawberries
- Provide the fruit, flavour and bulk of the preserve.
- Sugar
- Sweetens the preserve and draws out juice, and helps it thicken and keep.
- Cream of tartar
- Adds acidity that helps the sugar stay dissolved and supports a smooth, set texture.
The step that matters
Cooking the mixture on brisk heat. Once the juice starts, cooking too gently or too long can scorch the sugar or fail to reach the thick, gel-like set. Watch the pot and keep the boil steady for the full 20 minutes.
