Why do baked apple recipes usually call for butter? The apples don't taste buttery so what does the butter do!
Answers: Not only does butter add a distinct flavor, it is a browning agent. so if you want a nice golden brown on your crust, butter. Inside of a pie, it adds richnest and a velvity smoothnest that nothing else can mimic. Apple pie consist mainly of apples, flour, spices and then butter. It helps to bind all of the flavors and make it rich.
What ^ he said, and the butter kinda creates a nice caramel, when it melts with sugar.
