This has some really good information, great recipes, and would be very valuable if you live in or plan to visit Britain. You have the choice between using metric or imperial measurements, which is very valuable as well. In fact, my only real complaint is that the videos – which are quite good, by the way – download very, very slowly. This appears to be an app dedicated to a particular sous vide machine. Four stars for the slow downloads.
