Did you know that tomorrow is National Guacamole Day? Chances are you spend good money on avocados, so make them last longer by pickling them. It’s the best use for when you have unripe avocados and little patience for a brown paper bag incubator to do its thing. Those are the ones you actually want here—save the ripe ones for mashing onto toast—and it takes only a couple of hours for them to go from softball-level hardness to more manageable beach ball softness. Bonus: The vinegar helps keep them from turning brown, no lemon juice required.
