Where can one purchase a good quality cocoa powder?

* Grocery stores: Many grocery stores sell good quality cocoa powder, including brands like Hershey's, Nestle, and Ghiradelli.

* Specialty food stores: Specialty food stores often carry a wider variety of cocoa powders, including higher-quality brands and specialty varieties like Dutch-process or dark chocolate cocoa powder.

* Online retailers: Many online retailers sell cocoa powder, including Amazon, Walmart, and Vitacost. This can be a great option if you are looking for a specific type or brand of cocoa powder. Just be sure to read the reviews before purchasing to make sure you are getting a good quality product.

When choosing a cocoa powder, here are a few things to keep in mind:

* Look for cocoa powder that is labeled "unsweetened" or "pure cocoa powder." This means that the cocoa powder does not contain any added sugar or other ingredients.

* Check the fat content of the cocoa powder. Cocoa powder with a higher fat content will be richer and more chocolatey, but it may also be more calories. So try to find a cocoa powder with a fat content between 10% and 20%.

* Try to find a cocoa powder that is USDA organic or Fair Trade certified. This means that the cocoa powder was grown and processed in a sustainable way.
