The recipe only requires seven ingredients: butter, russet potatoes, heavy whipping cream, fresh thyme, truffle oil, shallots and sugar—plus salt and pepper, which is probably already in your ...
Assume a closed system (e.g. a container or process vessel), initially containing air, which shall be prepared for safe introduction of a flammable gas, for instance as part of a start-up procedure. The system can be flushed with an inert gas to reduce the concentration of oxygen so that when the flammable gas is admitted, an ignitable mixture ...
