Why?Ī: All oil infusion ingredients should be treated to kill anaerobic bacteria that can be present on the surface by pressure cooking or other suitable treatment. Q: I've seen the Porthole used for oil infusions but your instructions say not to use it with raw garlic. When re-inserting, please make sure the flat side of the gasket goes in the groove and the rounded edge faces the glass.

Is that supposed to happen?Ī: The silicone rubber gasket is removable and can come out of the groove. Many ingredient combinations, espacially oil infusions, can present a breeding ground for bacteria.įAQs Q: I disassembled my Porthole and the gasket came out of the groove. Observe sanitary practices to avoid food borne illness.Increased pressure inside the Porthole may lead to leaks. Do not insert stopper when infusing ingredients that expand in liquid, are carbonated, or that may ferment.For clean pour, pre-sift small particle ingredients such as tea before arranging in the Porthole. For best flow, always use the coarsest one suitable for your application. There are three screens that come with the Porthole.The screws hold the glass panes in place but gasket compression should come from squeezing the glass panes, not from torquing the screw. Squeeze the Porthole around the entire perimeter (like a steering wheel) to ensure that the gasket is properly seated before final tightening.Firmly squeeze the glass panes while tightening the second screw for proper seal.Tighten first screw with hex key for snug fit.First, gently press down a few spots around the perimeter, then push any loose sections down- wards into the groove.

When reinserting gasket, ensure its protruding leg is seated inside the groove, wider side facing out.

Gasket is removable and may become dislodged when the Porthole is disassembled.

We highly recommend that users familiarize themselves with the Porthole and its components by testing the Porthole with water before first use.
