Ingredients
Directions
The book says “a brisk oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Make a stiff paste with biscuit powder, milk, and water.
Add butter, egg yolk, and white sugar.
Cut into pieces and mold with your hands.
Bake the cakes
Bake in a brisk oven at 400°F (200°C) until not too thin.
Make the matzo batter
Warm 1 pint of water flavored with salt.
Mix 4 beaten eggs with matzo flour and milk.
Combine all together.
Finish in a tin
Bake in a tin.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Biscuit powder
- Provides the starch and flour base that turns the liquid into a stiff, shapeable paste.
- Eggs
- Bind the mixture and add structure and richness as they set in the heat.
- Matzo flour
- Supplies the starchy body that holds the batter together and sets it into a cake.
- Butter
- Adds fat that tenderizes the crumb and gives a richer flavor.
- Milk
- Adds moisture that hydrates the flours and keeps the dough soft.
- White sugar
- Adds sweetness and helps the surface brown in the oven.
The step that matters
Baking in a brisk oven. A hot 400°F oven sets the outside quickly so the cakes hold their shape. The record says to bake until they are not too thin, so watch the thickness rather than the clock.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
