Don't let either one burn you up. I think either burnt or dried is a good translation here. In English, "burnt alum" is the historical name for a heat-dried mineral alum.

Remember, they could not go down to the corner hardware store and buy a thermometer! I don't know the temperature at which feathers singe, but that is a common measure of how hot to make an oil -- until a feather just singes. If anybody knows the old cowboy recipe for boiled coffee -- egg shells are added to settle the grounds.

You don't drink the egg shells! I had an old German gentleman tell me very seriously that you shouldn't drink French wine because they put blood in it. I laughed at him until I discovered that a clarifying agent used to settle the dregs in french winemaking was once but no longer!
