Piping couplers aren’t the most exciting kitchen tools to talk about, but they’re one of the decorating staples that I reach for most often! These simple tools help attach your piping tips to a piping bag, and they make it very easy to switch tips multiple times using the same bag.
I like the Ateco brand because the tips of the couplers are simply round–some other brands have notches or cut-outs in the tips that make it hard to use them to pipe by themselves. The Ateco ones can be used plain for piping cupcake swirls, or used as intended as a coupler.
