I had never heard of lemon on pancakes! Made me realise that we have always eaten them in the Danish fashion, that is with raspberry or strawberry jam on them.
Probably because pancakes of this sort, are an English tradition, as is eating them on Shrove Tuesday, and it was more or less unknown in my Scottish childhood
In Denmark, Monday before Ash Wednesday is celebrated with sticky buns filled with custard and iced - the stickier the better and children used to go out guising for them. That stopped when Saturday morning school went out in the late 1960s, because Shrove Monday was no longer a half-holiday.
The logic, if such it is, being that unless it became an ordinary school day, it would not be possible to teach the stipulated hours a year! (They could just have deducted a day from the summer holiday, instead of ruining an ancient tradition!)
