Martha came across the recipe for these incredibly moist and delicious brownies in a cookbook. As it turns out, the recipe was developed by Elisabeth Luard, who happens to be the mother-in-law of Frances Boswell, food editor at Martha Stewart Living.
One cool thing about this sweet dessert is its freshness: Not cooking the cherries points up their peak-season taste. Another? You can use any red seedless jam for the glaze.
If you don't have a cherry pitter, a paring knife works well. Starting from the stem end, cut the cherry in half, going all around the pit. Pull apart the sides, and use the tip of the knife to push out the pit.
