The sweetness of the peaches and spiciness of the jalapeños make this a winning combination - all in jam form! It's a late-summer treat perfect for so many uses!
To easily peel peaches, blanch them in boiling water for 30 seconds. Remove from the water and place directly in ice water. Chill for 5 minutes and remove.
3 ½ pounds peaches
Discard peach skins, then cut peaches into thin wedges and discard pits.
In a large, heavy-bottomed pan, combine the peaches, sugar, lemon juice, vinegar, jalapeños, and rosemary. Bring to a rolling boil and reduce to a simmer. Simmer for 5 minutes.
Skim off any foam sitting on top of the mixture and discard. Press a piece of parchment paper directly on the peaches. Cover and chill for 4-6 hours.
After the mixture has rested, strain the liquid from the peaches. Remove and discard the rosemary.
Return the liquid to the pan and bring to a boil. Boil until the temperature registers 220°F to 225°F.
Add strained peaches and jalapeños back to the liquid and continue to boil for 5 minutes.
Remove from heat, and either can in a water bath or keep in the refrigerator for up to 2 months. Alternatively, this can be frozen for up to 1 year.
