Ingredients

1lbstrawberries

1½cupssugar

½lemon

1lbmixed berries,such as blueberries, blackberries, and raspberries

Preparation

In a large, nonreactive saucepan, toss the strawberries with the sugar and let stand for about 1 hour, stirring occasionally, until the sugar is mostly dissolved.

Squeeze the lemon over the strawberries, add it to the saucepan and bring to a boil, stirring until the sugar is dissolved. Cook for 5 minutes over moderately high heat, stirring until the strawberries are just softened.

Add the mixed berries and cook over moderate heat for 20 to 25 minutes until the liquid runs off the side of a spoon in thick, heavy drops. Skim off any scum that rises to the surface of the jam.

Discard the lemon and spoon the mixed-berry jam into 3 1 cup jars, leaving about ¼-inch of space at the top.

Close the jars and let the jam cool to room temperature.

Serve on toasts or scones, and enjoy!
