Re: UK members, custard apple cake question
To be honest i'm struggling to think. I can't think what you may not have in the US.
Apple cake covers such a wide variety of things
There are crumbles, crunchy on top and then fruit underneath but not generally sticky.
Maybe upside down cake? Apple or pineapple on top and spongecake underneath.
Steamed sponge pudding (they tend to be more domed in shape) that's quite moist and fruity on top. I guess that's the most british.
Apple drizzle cake.
Where abouts in the UK were you studying that may offer a few more clues.
