So there's a recipe for called delicious cake which is in a cookery book called simple recipes and menus for camp, home and nursery which was written by a woman called Lucy Khan who was actually living out in Calcutta at that time. Shall we have a go? Yes, I thought it would be fun if you make it recipe with a kitchen aid and I'm going to try and do it by hand like Lucy Khan would have had to. She wouldn't have had a kitchen aid, she would not. She might have had a servant but she wouldn't have had a kitchen aid. That's kind of what they ended up replacing really. So I've got my mixer on slow so I'm giving you a little bit of making it a bit more of a fair contest. Not really fair, Risa. Wooden spoon mixer. It's a little bit one-sided isn't it? So we're sticking to the original recipe. It's a bit lacking in instructions for methods if you don't have any idea about cooking it sort of. You'd have to know your way around the kitchen wouldn't you? You have a servant that moved the way around the kitchen. Exactly. And of course this is the moment where the servant crisis starts because so many women left domestic service to work during a wartime and then didn't go back. And then of course the story of the 20th century is in part how domestic appliances have helped and supplement labour in the kitchen. Certainly labour-saving, isn't it? It is. Yes, it's not you're gloating now. Lucy Khan didn't specify the number of eggs. Does she? She specifies the way to eggs. Yes, so it's quite weirdly you weigh them in the shells. You would think that you'd weigh them out of the shells. So you weigh an egg in a shell? Yes, so it's four ounces of eggs. Which equates to two eggs, fair of outs and yes. A bit of a lot of cookery books to choose from in those days. The British Library's got hundreds of thousands of cookery books but 1919 hardly any were published so this is quite unusual in a sense. So I'm giving it a final a call with so that all the ingredients are incorporated, how you go with the awesome you need a bit of extra elbow grease. I need a different arm. Here's my delicious cake. How are you going with yours? I'm nearly there. That was terrific. Lucy Khan would have been proud of you. She was sprinkling her success here. I'm coming up on the inside there. Good luck with it.
