Place fruit in a medium saucepan and cook covered over medium heat until the fruit comes to a boil, 12-15 minutes. Reduce heat to low and continue to cook, covered, as compote simmers. Stir occasionally to ensure nothing is sticking to the bottom. After 35-40 minutes, or when apples are completely soft, add honey, vanilla, and sea salt, and stir vigorously to break down fruit. Cook uncovered, another 8-10 minutes. Remove from heat and transfer to clean, air tight jars. Seal and let cool, then refrigerate. Will keep a few weeks in the fridge.
