Cleaning a blender jar can be an annoying and tricky task. Taking it apart is easy, but then suddenly you have four pointy blades in your hand, and then there’s the gasket, which is easy to lose. Fortunately, there’s a better and safer way. Without taking the jar apart, fill it about one-third full with warm water and add a squirt of dishwashing soap. Put the lid on, return it to its base, and turn it on for a few seconds—it’ll practically clean itself. Pour out the water, sponge off any residue from the jar and lid, and rinse.
