 So there's a recipe 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 Kahn, who was actually living out in Calcutta at that time. Shall we have a go? Yes, let's have a go. I thought it would be fun if you make it a recipe with a KitchenAid and I'm going to try and do it by hand, like Lucy Kahn would have had to. Yes, she wouldn't have a KitchenAid, would she, back then? She would not. She might have had a servant, but she wouldn't have had a KitchenAid, that's kind of what they ended up replacing really. So Polly, 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. It's not really fair, is it? Well, 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 method. If you didn't have any idea about cooking, it's sort of... You'd have to know your way around the kitchen, wouldn't you? You'd have a servant that moves 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 sort of help and supplement labour in the kitchen. Certainly labour-saving, isn't it? Yes, you're gloating now. Lucy Kahn didn't specify the number of eggs, does she? She specifies the weight of eggs. Ounces, yes. So it's quite weirdly. You weigh them in the shells. You know, 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 ours. Yes, yes. There are a lot of cookery books to choose from in those days. You know, 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 little whisk so that all the ingredients are incorporated. How are you going with yours? Do you need a bit of extra elbow grease? I need a different arm. Polly, here's my delicious cake. How are you going with yours? I'm nearly there. That looks terrific. Lucy Kahn would have been proud of you, I think. She was, sprinkling of success here. I'm coming up on the inside, though. Good luck with it.
