Microwave Cherry Preserves

Microwave preserves are the smartest small-batch canning trick most home cooks have never tried. The microwave cooks fast and even, the bowl holds the bubbling fruit safely, and the whole process happens in three short bursts instead of an hour at the stove.

Use a large 3-quart microwave-safe bowl. The fruit boils up dramatically as the pectin sets, and a smaller bowl will overflow into your microwave faster than you can stop it.

Fresh pitted cherries give the brightest flavor, but frozen pitted cherries work too if you thaw and drain them first. Sour Morello cherries make a more complex preserve, while sweet Bing cherries give a milder, candy-like result.

The almond extract is the trick that turns ordinary cherry jam into something memorable. Cherries and almonds are botanical cousins (both stone fruits in the rose family), and a half teaspoon of almond extract amplifies the cherry flavor naturally rather than masking it.

The sheet test is your set test. Dip a cold spoon into the preserves and lift. If the last drips run together into a sheet rather than dripping individually, the pectin has set.

Pro Tips

• Use a wood or silicone spoon for stirring. The bowl gets searing hot in the microwave.
• Skim the foam off carefully before jarring. Foam looks cloudy in the finished jar.
• Sterilize jars with boiling water before filling. Hot fruit into cold jars cracks the glass.
• The water-bath process at the end is essential for shelf-safe storage. Don’t skip it.

Variations

• Stir in a tablespoon of kirsch or amaretto off the heat for boozy depth.
• Add a split vanilla bean to the cooking pot for a vanilla-cherry preserve.
• Swap a quarter cup of the sugar for honey for a floral, slightly looser preserve.
