We wanted to find funnels that wouldn't back up or wobble when filled.
In the test kitchen, we use funnels to transfer liquids and oils, fill pepper mills, and refill spice bottles. But poorly designed funnels can back up or wobble when filled, and they are often bulky to store. We tested seven brands, including funnel sets, collapsible and flexible silicone models, and one that offers a spout that opens and closes. Our favorite has a generous 1-cup capacity, smooth and sturdy walls to let liquid and dried herbs slide down easily, and a 1-centimeter-wide spout that is narrow enough to fit into most small-necked bottles, yet wide enough to prevent backup of thicker liquids. It collapses from 5 inches to 1¾ inches, making storage easy, and is reasonably priced.
