Method
Macerate the peaches
- Combine the peach chunks with granulated sugar and lemon juice, then macerate for 1 hour so the peaches release syrup.
- Stir the mixture once halfway through the 1-hour maceration to help the sugar dissolve.
Cook to thick preserves
- Pour the macerated peaches into a heavy pot and bring to a boil, stirring, until you see active bubbling.
- Reduce to medium and cook for 35 to 45 min until thickened with large bubbles, stirring occasionally to prevent sticking.
Finish and jar
- Stir in fresh rosemary and vanilla extract during the last 5 min of cooking so the herb stays bright.
- Test for set, then ladle into sterilized jars while hot.
- Process in a canner for 10 min, or refrigerate for up to 1 month instead of processing.
Notes
Pro tip: if your preserves aren’t thickening after 35 min, keep cooking in 5-minute increments until large bubbles persist and the set test holds. Refrigerate up to 1 month; freeze only if jar-free (about 3 months) for best texture. For a lower-sugar swap, use a no-sugar-added pectin system instead of granulated sugar so the fruit sets properly without changing the finish steps.
