Lemon Cookies

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.

Prepare the dough

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

  2. In a large bowl, cream together the butter and sugar.

  3. Add the lemon juice and grated peel, mixing well.

  4. In a separate bowl, whip the eggs until light and fluffy, then add to the mixture.

  5. Dissolve the baking soda in the milk and add it to the dough.

  6. Gradually add the flour until a stiff dough forms.

Shape and bake

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

  2. Bake until light brown.

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

What each ingredient does

Butter
Creams with the sugar to give the cookies richness and a tender crumb.
Sugar
Sweetens the cookies and helps them brown as they bake.
Eggs
Add structure and richness, and whipping them lightens the dough.
Flour
Forms the stiff dough structure that holds the cookie shapes.
Baking soda
Reacts with the acidic lemon juice to help the cookies rise and brown.
Lemon juice
Adds acidity and bright lemon flavour, and works with the baking soda.

The step that matters

Gradually add the flour until a stiff dough forms. Adding flour gradually lets you stop once the dough is stiff enough to roll. Too much flour makes the cookies dry and tough, while too little leaves the dough sticky and hard to cut.

Swap the lemon
