Review on Reusable Silicon Trivet Rack Lifter With Handles - Compatible With Instant Pot, Ninja Foodi Pressure Cookers - Fits 5-Quart 6-Qt 8-Qt Silicone Bakeware Sling by Darius Glatzel

Design-wise, portions of the bottom are flat (for example the egg circles) on this silicone bakeware sling, so presumably water wouldn’t circulate as well in those spots, creating hot spots. For example if you pour water in the center hole, it stays there and doesn’t seep out the bottom. Some arches/notches might alleviate that.In testing "hard boiled” eggs (1c water, 6min high, QR), if done with the pointy end down, the shell cracks during cooking, while if done pointy end up, the shell stays undamaged. The cracks seem to form late in cooking after the white’s solidified, as there isn’t a mess of egg goo in the pot and the whites are intact (unlike when they crack during regular boiling). This actually makes them even easier to peel, though some of the air pockets get slightly toasted. I’m too lazy to work through the science, but I’d guess it has something to do with temperature differentials, thermodynamics, and pressure as caused by the hot/dry spots created and how the egg orientation affects the seal with the hole.It fits a 6-qt IP Ultra with a small gap - efficient use of space, but not so tight you need to position it juuuust right to seat properly. Decently thick to maintain structure, which is particularly helpful for the handles, so they don’t sag into your food. Handle lock/connector is a bit tight when cold (loosens up a bit after cooking), but that just means it’s more secure. I wouldn’t cook a whole chicken directly on it, as it’d be a giant pain to clean afterwards, at least by hand, due to all the nooks and crannies.
