SO I was glad she finally found her cap, well it should be under the hat..., went to all that trouble of doing a video in a period kitchen and to try and dress the part, BUT no cap nor bonnet when cooking ???..., she should stay away from Masterpiece Theater's version of Pride and Prejudice when deciding what to wear...., you don't have to actually pretend to be in the first decade of the 19th Century to do a cooking video on a recipe from then... chef Walter Staib who does A Taste of History doesn't, BUT if you do decide to dress the part, then..., do it right.
"Lard" is not trimmed (salted) bacon fat..., you don't want to put that with that much salt, into one's hair. That would have much more salt than modern bacon (which is what she used as it was so soft). Bacon fat is for cooking, only, at that time period.
