Once upon a time, Mason jars were invented to preserve food...then Pinterest came along. Whether you love them or hate them, Mason jars are undeniably multifunctional and when Karen Rzepecki began using her jars for shaking up homemade dressings, she figured out how to make them even more user-friendly. Enter reCAP, a line of specialty lids to fit most Mason jar brands and sizes. The original Pour cap is perfect for salad dressings, but we love the new additions of Adapta—a pump or spray top that’s ideal for olive oil—and Flip, which transforms your jar a shaker for everything from powdered sugar to sesame seeds with the addition of a screen attachment.
