Wooow, what a cool topic and what wonderful diversity!
I never had butter on my pancakes, but I embrace the idea!
Traditionally, local pancakes are inbetween crepes and thicker pancakes...some strive to make them thin, and it's easy to do with regular flour, and 'pale' (my daughter likes them as thin and as pale as it gets), with any kind of jam or marmalade.
She likes apricot jam. I love (low sugar) any jam/marmalade.
That's the traditional, basic filling. Rolled, or folded in 4.
Of course, she loves Nutella, fresh strawberies and whipped cream too.
Her Grandma does ground walnuts, ground biscuits and honey.
I'd eat a pancake with cream cheese and fresh fruit, caramel sauce over vegan cream. I've tried ( long time ago), a cottage cheese,raisins,lemon(zest and juice), sugar filling ( you can get those in restaurants too, it's lovely), if I am out of jam, a teaspoon of honey will do.
My gluten free pancakes tend to be thicker, as I vary the flours/nuts/seeds in the batter.
My Grandma baked a large pancake in the oven, and we'd smear slices with marmalade, usually her home made ones.
Shopping malls do offer mini pancakes and American pancakes, I ve not/can't, tried them. My daughter has.
I loved the crepes with ice cream in France, would eat that.
