Anyone have any experience cooking portabello mushrooms sous vide? Any suggestions for temperature, duration, and liquid? I've seen a reference to a few hours at 105 in a raw food focused blog, but no real details. Thinking of whipping up a chicken and portabello dish for dinner tomorrow night. Thanks in advance, all. A wealth of information here. FYI, my two sous vide rigs are an ICA SideKIC (a good option for <140 degree cooks but underpowered above that), and a homebrew setup that features an Igloo Ice Cube, in which I've used a soldering iron to melt channels for the requisite wires, with a 1000w bucket heater and an aquarium pump suspended on an aluminum bracket that clips into the ridges in the cooler, and a DorkFood DSV controller.
