Peach and Lemongrass Butter

 

about 2 lbs (1 kg) ripe, fragrant white or yellow peaches

1 cup (200g) sugar, or to taste

4 fat stalks lemongrass, roughly chopped

2 tablespoons lemon juice, or to taste

 

Bring a large pot of water to a rolling boil. Blanch the peaches by submerging them (in batches, if necessary) for 1 minute and then transferring them to a bowl of ice water. When cool, peel, pit and slice them. Combine them with the sugar in a large bowl and let macerate at room temperature for a couple of hours, during which time the peaches should give up a lot of juice. Strain the peaches, reserving the juice. Place the juice, the sliced lemongrass and 1 cup water in a heavy-bottomed pot and bring to a boil over medium-high heat. Reduce the heat slightly and let simmer until you have a thick, fragrant syrup, about 30 minutes. Strain the syrup, discarding the lemongrass. Return the syrup to the pot and stir in the peaches. Simmer over medium-low heat until the peaches are completely soft, about 20-25 minutes. Remove from the heat and puree, either in a blender or with an immersion (stick) blender. Return to the pot and stir in the lemon juice. Cook over low heat, stirring frequently to prevent scorching, until the puree thickens to the consistency of applesauce, about half an hour. Taste the mixture and add more sugar or lemon juice as desired. Remove from the heat and transfer to a closed container (or, if you’re comfortable with canning, fill into jars and process in your normal way). If not canning, refrigerate immediately and consume within a couple of weeks.
