Instructions
Combine fruit and sugar in a medium saucepan. Let macerate for at least 30 minutes and up to several hours at room temperature.
Once the fruit has macerated, set the saucepan on the stove over medium-high heat and bring the mixture to a boil—just keep a watch so it doesn’t boil over. Encourage the berries to break down by gently smashing them with a wooden spoon.
Continue to cook, scraping the bottom frequently and using your spoon to smash and further break down the berries, until the mixture reduces and thickens into a texture that can only be described as jammy, 15 to 20 minutes. Reduce heat to medium-low to low, stir in the lemon juice and salt, and continue to cook for 10 minutes, stirring often. Taste, and add more lemon juice if you want things a bit more tart.
If you’d like, now is also the time for your add-in(s). Stir until combined. Remove from the heat and let the jam cool. If using fresh herbs in the jam, remove them after 30 minutes and discard. Transfer jam to a clean mason jar with a lid that seals—make sure there’s a bit of space between the top of the jam and the jar lid. Store in the fridge and use within 3 weeks.
