Why it works: Flour and raisin match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Watermelon Cake
Ingredients
Directions
The book says “a rather slow oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the egg whites and mix well.
In a separate bowl, combine the flour, cream of tartar, and baking soda.
Gradually add the dry ingredients to the butter mixture, alternating with the sweet milk.
Take a little more than half of the batter and mix in the liquid cochineal and raisins.
Pour the red batter into the center of a greased cake pan and then pour the remaining batter around it.
Bake until a toothpick inserted in the center comes out clean.
Once cooled, cover the cake with green frosting.
