Lemon Crackers

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

  1. Preheat your oven to 350°F (175°C).

  2. In a large bowl, beat together the sugar and eggs until well combined.

Make the dough

  1. Add the lard and milk, mixing until smooth.

  2. Stir in the baking ammonia and lemon oil.

  3. Gradually add flour until the dough is stiff enough to roll out.

Shape and bake

  1. Roll out the dough and cut into desired shapes.

  2. Place on a baking sheet and bake for 10-12 minutes or until lightly golden.

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.
Sugar
Adds sweetness and helps the crackers brown lightly in the oven.
Lard
Adds fat that keeps the crackers tender and short.
Milk
Adds moisture that combines with the flour to form the dough.
Baking ammonia
Releases gas during baking to lighten the crackers and help them rise.
Flour
Provides the structure that holds the stiff dough and its shape.

The step that matters

Add the flour gradually until the dough is stiff enough to roll out. Flour absorbs liquid and builds gluten, so adding too much makes the crackers tough and dry, while too little leaves a sticky dough that spreads and bakes unevenly.

Swap the lemon

How well each one fits the dish's main ingredients (sugar, egg, milk, flour):

Fit is the average pairing score against sugar, egg, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
