Ingredients
2 lbs ripe nectarines (about 6-8 medium)
2 cups granulated sugar
2 tablespoons fresh lemon juice
1/2 teaspoon unsalted butter (optional, to reduce foaming)
Instructions
Wash, pit, and chop nectarines into 1/2-inch pieces (do not peel). Place in a large, heavy-bottomed pot.
Add sugar and lemon juice; stir to combine. Let sit for 10-15 minutes until nectarines release their juices.
Place pot over medium-high heat and bring to a boil, stirring frequently. Add butter if using to reduce foaming.
Once boiling, reduce heat to medium and cook at a steady boil, stirring often, for 20-30 minutes until jam thickens and reaches 220°F (105°C) on a candy thermometer, or passes the plate test (a small dollop on a cold plate wrinkles when pushed).
Remove from heat and let cool for 5 minutes. Skim off any foam if desired.
Ladle jam into sterilized jars, leaving 1/4-inch headspace. Wipe rims, seal, and process in a boiling water bath for 10 minutes for shelf stability, or refrigerate for up to 3 weeks.
Tips
For a smoother jam, peel nectarines before chopping.
Store in the refrigerator for up to 3 weeks, or freeze for up to 6 months.
Adjust sugar to taste; reduce by up to 1/4 cup if nectarines are very sweet.
