Why it works: Lemon and cinnamon match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 7,950 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓

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.
Make the dough
Dissolve the yeast cake in warm water and add it to the scalded and cooled milk.
Mix in enough flour to make a stiff batter and let it rise until light and bubbly.
Add melted butter, sugar, salt, beaten egg, lemon rind, and more flour to make a stiff batter. Beat well.
Let the mixture rise until it doubles in bulk, then spread it in a dripping pan.
Cover and let it rise again.
Bake and serve
Once risen, brush the top with beaten egg and dust with sugar and cinnamon.
Bake in a hot oven at 400°F (200°C) for twenty minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Yeast cake
- Ferments the dough, producing gas that makes it rise and turn light and bubbly.
- Flour
- Forms the gluten network that gives the batter its structure and holds the rising gas.
- Egg
- Adds structure and richness, and the beaten egg brushed on top helps the surface brown.
- Butter
- Adds fat for a tender crumb and rich flavor.
- Sugar
- Feeds the yeast and adds sweetness and browning on the dusted top.
The step that matters
Let the dough rise until it doubles before baking. Yeast gas must fully expand the dough before the oven sets its structure. Underproofed dough bakes dense, while overproofed dough can collapse.
