Ammonia Cookies are a traditional old-fashioned treat popular in early American baking. Known for their soft, tender crumb and subtle flavor, they use baker’s ammonia (ammonium carbonate) instead of baking soda or powder. This leavening agent was common in 19th-century European and American kitchens, lending a crisp, airy texture. The inclusion of lard and sweet milk reflects the ingredients available to home bakers at the time. Though ammonia might seem unusual today, it evaporates during baking, leaving no taste behind, just light and delightful cookies reminiscent of another era.
Cream together the lard and sugar until light and fluffy.
Step 2: Add Liquids and Eggs
Beat in the eggs one at a time. Add the milk and lemon oil and mix until well combined.
Step 3: Add Dry Ingredients
Dissolve the baker’s ammonia in a small amount of warm milk if needed. Add it to the mixture along with salt. Gradually stir in flour until a stiff dough forms.
Step 4: Shape Cookies
Roll out dough on a floured surface to about ¼ inch thick. Cut into desired shapes using cookie cutters.
Step 5: Bake
Place cookies on a greased or parchment-lined baking sheet. Bake at 350°F (175°C) for 10–12 minutes or until edges are lightly golden.
Tips
Substitute shortening or butter if lard is unavailable.
Add a bit of vanilla or nutmeg for a modern flavor twist.
Store in an airtight container to maintain texture.
