These two common Nigerian snacks are very similar, but to what extent?
Let's see the difference between scotch egg and egg roll.
Egg roll is more similar to Nigerian buns than scotch egg. It is made by deep-frying dough wrapped around a hard boiled egg. It is totally different from the Chinese egg roll.
Scotch egg on the other hand is made of seasoned mashed sausage meat, wrapped around a hard boiled egg, dipped in egg and bread crumbs.
The only similarities are that they are pastries that hold eggs in them and are fried.
