Final answer:
Soy milk can generally be used as a one-to-one substitute for dairy milk in most recipes, but it may change the flavor and texture slightly due to differences in fat content.
Step-by-step explanation:
True, soy milk can typically be substituted measure-for-measure in recipes calling for dairy milk. This includes a variety of recipes such as sorbet, marinara sauce, meat sauce, white milk sauce, and hot cocoa. However, it's important to note that soy milk may alter the taste slightly and might not behave exactly the same in certain recipes, especially when it comes to texture or how the milk reacts to heat. For recipes that rely on the fat content of milk for creaminess or thickness, soy milk, which has a different fat content than cow's milk, might not yield the exact same results.
