You can use any stone fruit or berries you like; just adjust the amount of sugar and lemon juice to get a mixture that’s sweet but not cloying, and with enough acidity to taste a bit sharp. (Many plums and berries won’t need any lemon juice.) You can make it in a baking dish, as I do, a pie plate or even a cast-iron skillet. In any case, the result will be a rustic but delicious pie-like dessert.
