It may come as a surprise when you first see 'Kipper' on the menu, but they are relatively common and are virtually identical to those eaten in the UK. However, in Flanders they are normally served for lunch and accompanied by boiled potatoes.
The French find it very difficult to understand how we could possibly eat them for breakfast, their loss I guess, but on second thoughts....ever tried dunking a Kipper in 'chocolat chaud'?...just wouldn't work, would it?
