I wait till Lidl and Aldi will offer Haggis here in Bavaria.
But I think they will not.
Different country different tastes.
But I do a lot of "exports" always, when going back from Portugal.
Olive oil, smoked ham, and a smoked pork knuckle.
Those are my specials.
Preparing your own haggis?
Not so easy I suppose.
First you must have all those ingredients, which are not easy to get I suppose.
I was reading about, mainly made after a slaughtering and butchering.
