Ingredients
2 lbs fresh fruit (e.g., strawberries, peaches, or mixed berries), washed and chopped
2 cups granulated sugar
1/4 cup lemon juice (about 1 lemon)
1/2 tsp butter (optional, to reduce foaming)
Instructions
In a large, heavy-bottomed pot, combine the fruit, sugar, and lemon juice. Stir well and let sit for 10-15 minutes to macerate.
Place the pot over medium-high heat and bring to a boil, stirring frequently. Add the butter if using to reduce foaming.
Once boiling, reduce heat to medium and cook at a steady boil, stirring often, until the mixture thickens and reaches the gel point (about 20-30 minutes). To test, place a small plate in the freezer; drop a spoonful of jam on the cold plate; if it wrinkles when pushed with a finger, it's done.
Remove from heat and let cool for 5 minutes. Skim off any foam if desired.
Ladle the hot jam into sterilized jars, leaving 1/4-inch headspace. Wipe rims, seal with lids, and process in a boiling water bath for 10 minutes for long-term storage, or refrigerate for up to 3 weeks.
Tips
For a lower-sugar version, use a no-sugar-needed pectin and reduce sugar to 1 cup.
Store opened jam in the refrigerator for up to 3 weeks.
To test for doneness without a thermometer, the jam should reach 220°F (105°C) at sea level.
