Cake mix cakes and scratch-made cakes can have different qualities and flavors due to several factors, including ingredients, preservatives, and freshness. Here are some of the key reasons why cake mix cakes might develop a sour taste more quickly compared to scratch-made cakes:
Preservatives: Cake mix products often contain preservatives to prolong shelf life and maintain freshness. These additives can affect the taste and texture of the cake, and over time, they may contribute to an off-flavor or sour taste.
Quality of ingredients: In many cases, scratch-made cakes use higher-quality ingredients compared to cake mixes. For example, fresh eggs, real butter, and high-quality flour can contribute to a better taste and longer-lasting freshness in scratch-made cakes.
Artificial flavors: Cake mixes may contain artificial flavors or extracts, which can impart an artificial taste and might not hold up well over time, potentially leading to a sour or off-flavor.
Freshness: Scratch-made cakes are typically made from scratch (hence the name), meaning they are made using fresh ingredients and don't sit on the shelf for an extended period before baking. Cake mix products, on the other hand, have a longer shelf life, and as they age, the flavor may degrade, resulting in a sour taste.
Chemical leavening agents: Cake mix recipes often include chemical leavening agents like baking powder, which can affect the pH of the cake. If not appropriately balanced or if the cake mix is not used promptly, it may contribute to a sour taste over time.
Storage conditions: How a cake is stored can also impact its flavor and freshness. If a cake mix cake is not stored properly or if it's left at room temperature for an extended period, it may go stale or develop off-flavors more quickly.
When making a scratch-made cake, you have more control over the quality and freshness of the ingredients, as well as the absence of certain additives that may contribute to an unpleasant taste over time. This can result in a cake that stays sweeter and more enjoyable for a longer period compared to cake mix cakes. However, it's essential to note that both scratch-made and cake mix cakes can stay fresh and delicious when stored properly and consumed within a reasonable timeframe.
