The five basic food groups.
There is a huge fish-eating culture here. Although the cured herring makes me gag, I'm rather partial to hot smoked salmon and have been eating it almost every other day.
A favourite past time of Finns (young and old) is to go berry-picking in the forest during the summer. Wild strawberries and blueberries are my favourite.
Finns sure love their dairy products. Everyone here seems to have a glass of milk with their main meal. Even better than regular milk is something the finns call piima...sour milk.
White bread is hard to find here in Finland. Rye is the default.
Salty licorice (ammonium chloride). The same stuff comes spewing out of volcanos and gets left behind when you burn coal.
