Finnish cuisine does not differ much from Swedish and Russian ones, except Swedish is more sweet and Russian may be more salty. German and Baltic cuisines are not so distant either.
The traditional Finnish cuisine has been quite rich in calories simply due to the fact that people consumed a lot of energy. Today the diet has to be more light of course, since very rare people have so physical work that requires large intakes in calories. But if traditional cuisine is followed, a diet would contain meat, lots of dairy products, sour rye bread, roots (such as carrots and turnips), arctic berries, mushrooms, vegetables. This kind of a diet (partially based on hunting and gathering) would be the most healthy for me also because of being pretty much CM also by metabolism.
Some of my favourites:
- dairy products in any forms (cheeses, youghurt, viili (processed sour milk), sour milk)
- creamy salmon soup
- fish in many forms, preferrably smoked
- different kinds of pasties
- pancakes with arctic berries
- game such as elk (reindeer is exotic, definitely delicious but eaten on daily basis only in Lapland)
- sour rye bread, most preferably baked with moderate heat and for a long time
- meatballs (ground meat, eggs, chaffed onions, oat flakes and spices)
- pea soup with smoked pork and mustard
- fish roe, preferrably smoked too... but salted is good too
- creamy tomato soup (dunno from which cuisine this is originally from)
- and last but not least, tomato in almost all forms
Additionally, besides typically Finnish cuisine, I have to admit that I'm fond of....
... American cuisine
Meaning a cuisine that has Italian and Mexican influences, the original Italian is delicious of course, by default (I love pesto and especially tomatoes, did I mention that already?
) but original Mexican food is simply disgusting. Mexican food American style is very delicious though.
