Mmm I love American banana pudding, which seems to be banana, some sort of biscuit or cake and shit loads of cream mixed together. Heavenly.
And layers of custard. Banana pudding is essentially a trifle. It is indeed delicious and the iconic dessert of the southern US.
It’s a strange food culture, but no stranger than ours, I guess. I’ll never forget the first time my Italian friend had a roast dinner and her utter revulsion at gravy
Likewise, I will never forget the second or third day when I was first in the UK as a student and was served beans for breakfast.
By the way, those of you objecting to gravy on biscuits; that's regional within the South and seems to have migrated to much of the rest of the country. In my part of the South, it's just butter and jam or, my favorite, butter and honey. And of course, the biscuits have to be made well: crusty on the outside and soft and fluffy on the inside. If you want good biscuits, come to Georgia.
