I love this channel. They show 18th century food preparation and preserving food. They do it in full costume over a wood fire. They did deviate once by showing how to make 18th century beef broth cubes in a slow cooker.★
They also showed different methods that were used to preserve eggs.
They even have videos about 18th century methods of making earthen and mud ovens.
