According Jarosch Bakery, the reason that cakes from the supermarket taste very different from cakes from a local bakery is that supermarkets make their cakes in bulk with lower cost ingredients, so they can produce larger quantities. Although these cakes are made in large quantities, they lack craftsmanship, detail and, most importantly, quality ingredients.
baby food compares the difference in ingredient lists in cakes made from major grocery chains such as Harris Teeter, Costco, and Fresh Market, and finds that it’s just one great science experiment. By this, she means that many ingredients are unrecognizable and difficult to pronounce, which indicates preservatives and processed ingredients, and can potentially lead to health issues.
Not only are local bakeries more likely to use fresher, quality ingredients, but they generally have more unique products to choose from because they don’t need to keep up with the masses. They can think outside the box of brownies and chocolate chip cookies, and gravitate towards babkas, scones, macaroons, and more, all while adding unique flavor combinations to the mix (via bakerycity).
Local bakeries also play an important role in small communities and are usually family run. When you donate your business to large grocery chains, you are supporting a CEO, versus a neighbor.
