Can you use horn salt in a cake instead of baking powder?

You cannot use horn salt (also known as ammonium chloride) in place of baking powder in a cake.

Here's why:

* Horn salt is a chemical salt, not a leavening agent. Baking powder is a mixture of chemicals that release carbon dioxide gas when mixed with liquid, causing the cake to rise. Horn salt does not have this property.

* Horn salt is toxic. While small amounts might be used in certain food preparations (like certain candies), using it directly in a cake would be dangerous.

Instead of horn salt, you can use:

* Baking powder: The most common and effective leavening agent for cakes.

* Baking soda: If your recipe calls for an acidic ingredient like buttermilk, you can use baking soda instead of baking powder.

Always be cautious when using any ingredients in your baking. If you are unsure about a substitute, it's best to stick with the original recipe or consult a reliable baking resource.
