Smörgåstårta. I have learned that this is very Scnadinavian, almost only Swedish. Not too many outside Sweden has even heard of this.

What is a Smörgåstårta? It's a kind of birthday cake, but instead of whipped cream, you use salmon, shrimps, caviar, cheese, roast beef etc. It's delicious.

Now try it, before you think of it.
Think of this:

1. Avoid blue cheese, it gets too strong.
2. Save the expensive stuff for ganration.
3. Don't use too much mayonaise, mix it with sour creme etc. instead.
4. Save the shrimp shells and boil them separate. Save the bullion and boil some cheaper fish (cod) in the bulion. You can use the fish and mix with the shrimp/prawns in a middle layer. No one can tell.

Bottom layer: bread, puzzle it together if you can't find long big slizes of bread. On this you add a mix of mild cod caviar and sour creme.
Add another layer of bread. Next layer: Krabbmix, fish-prawn-shrimp mix.
Add another layer of bread. Top, garnate with shrimps, eggs, mayoniase. Decorate with slices of lemon, dots of caviar etc. Just make it nice, o.k?
