Ingredients

Directions

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

Make the dough

In a bowl, mix the eggs, sugar, butter and lard, sweet milk, baking powder, salt, and flavoring until very soft.

Shape and bake

Roll the dough thin and sprinkle with sugar.
Bake in a quick oven at 400°F (200°C) until golden.

Recipe from a historical cookbook (Internet Archive).

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.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs: Bind the dough and add structure and richness as it bakes.
Butter and lard mixed: Add fat for tenderness and a short, crisp texture.
Baking powder: Releases gas in the dough, helping the cookies rise and lighten.
Sugar: Sweetens the dough and helps the surface brown as it bakes.
