Swedish Lax Pudding

This dish was taught to me by a good friend and Swedish chef. Ever since then, around Christmas time, when attending quite a number of pre-Christmas parties that are “potluck”, meaning they require all participants to bring a dish along, I make this Swedish lax pudding. It is so simple, needs little to none care except reheating and is always well liked.
As often the case with traditional recipes there are no strict rules and therefore instead of salted salmon one could easily use cold smoked salmon or even raw, sautéed salmon and the dish would taste just as good.
