Baking is both an art and a science, filled with nuances that can affect the outcome of your culinary creations in surprising ways. While most of us are familiar with the basics of baking, here are a few questions that often go unasked. 

Can Flour Go Bad?

Yes, flour can go bad. Despite its dry, powdery nature, flour is not immune to spoilage. White flour, which is more processed, can last up to a year if stored in a cool, dry place. Signs that flour has gone bad include a rancid smell, a clumpy texture, and any evidence of pests. 

Does Brown Sugar Make Your Cookies Chewier? 

Not necessarily! The chewiness stems from the molasses content, which is present in both brown and white sugar. Brown sugar’s additional moisture can lead to denser cookies, while white sugar creates airier textures. Ultimately, the choice boils down to flavor preference.

Does Baking Soda Expire?

While baking soda can last a long time, it does lose potency over time. An unopened package can be effective for up to two years, but once opened, use it within six months. To test if your baking soda is still active, mix 1 teaspoon of baking soda with 3 teaspoons of vinegar. If it bubbles, it’s still good to use.
