This recipe started the way all jam recipes should: I came into a bounty of stunningly delicious, in-season fruit. It wasn’t from a blueberry patch like those in southern Maine my homesteading sister, Rebekah, picks from, but it was the closest thing I have to such: the Dupont Circle FreshFarm Market. One of my favorite vendors there, Tree and Leaf, had blueberries one summer that were better than any I’ve tasted outside Maine. I paid a pretty penny for them, went home, and broke open Mes Confitures, the tome by famous French jam maker Christine Ferber. I found her take on a wild blueberry–lemon jam, and I took shameless liberties with it, as anybody working with much different fruit should. I used much less sugar (her wild ones must be very tart), and streamlined the process. The result is a celebration of the blueberry, brightened with slices of candied lemon, peel and all. Use it anytime you want good jam: on toast, stirred into yogurt, and even as the basis of such desserts as Blueberry-Lemon Tart with Toasted Coconut (page 165).
If you don’t want to fully seal and can the jam, you can pack it into clean jars, tighten the lids, let cool to room temperature, and refrigerate for several months. Or pack into freezer-safe plastic bags, squeeze out the extra air, seal, and freeze for up to one year.
