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 ↓

Yeast Cake

Oven, in the book's wordsA hot oven

Ingredients

Directions

The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Dissolve the yeast cake in lukewarm water.
In a bowl, combine butter, sugar, and salt with lukewarm milk.
Add the dissolved yeast, cinnamon, flour, and beaten egg; mix thoroughly.
Fold in the raisins or currants, cover, and let rise overnight.
In the morning, shape the dough into buns and place them in a pan one inch apart.
Let the buns rise, brush with beaten egg, and bake at 400°F (200°C) for 20 minutes.
Cool the buns and decorate with ornamental frosting to make a cross on top.
