Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
Beat the eggs in a large bowl.
Add the sugar, butter, and flour and mix well.
Dissolve the baking soda in the milk and stir it into the mixture.
Add the lemon extract and grated nutmeg and mix until combined.
Fold in the citron pieces.
Bake
Pour the batter into a greased baking pan.
Bake at 400°F (200°C) until golden.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure as they set in the oven.
- Butter
- Adds fat for a tender crumb and rich flavour.
- Flour
- Forms the structure that holds the cake together as it bakes.
- Baking soda
- Reacts with the batter to help it rise and lighten the texture.
- Sugar
- Sweetens the cake and helps it brown as it bakes.
- Citron
- Adds candied fruit pieces that give bursts of tart, sweet flavour.
The step that matters
Dissolving the baking soda in the milk. Baking soda needs to be fully dissolved so it spreads evenly through the batter. Undissolved pockets can leave bitter spots or uneven rising.
