“A Brief Guide to Sous Vide at Home“. I have made this available as an eBook (Kindle) on Amazon. Details here.
The eBook is a slightly edited version of the PDF that was available from the Downloads page of this site (now removed). If you already have that, then this eBook doesn’t contribute much more. If you would like the eBook version anyway and have paid for the PDF, contact me and I will send a complementary copy.
