As it turns out, baking cookies is actually a combination of both chemical and physical changes. The heat from the oven causes the ingredients to undergo a chemical reaction, breaking down the molecules and reorganizing them into something new. It's like a game of molecular LEGO, where the pieces get rearranged to create a delicious, chewy cookie!
But what about the aroma that fills your kitchen when you're baking? That's a result of the Maillard reaction, a chemical reaction between amino acids and reducing sugars that creates those yummy, caramelized flavors. It's like a symphony of molecules playing together in perfect harmony!
Now, you might be wondering, what about the physical changes that occur during baking? Well, when you cream together butter and sugar, you're creating a physical mixture that's still made up of the same individual ingredients. But as you add in flour and other dry ingredients, the mixture starts to take on a new texture and structure, thanks to the formation of gluten networks.
