When I grew up we had this sausage made in three versions.
1) you slice it into 1/4 inch slices and panfry it, and serve with mashed potatoes and ketchup.
2) you cut it into 1/4 inch thick sticks and make something called 'sausage stroganoff' with it, including lots of ketchup and cream.
3) you keep it whole, but slice it 2/3rds through and put slices of apples, onions and cheese into the cuts, and then bake in the oven. Ketchup and more cheese is good on top!
Both 1 and 2 were served as lunch food in the public schools.
I don't really miss falukorv here in the US, and for me this is real childhood food. And yes, there was lots of ketchup when I grew up. Next week we will go on to another Swedish childhood food - blood pudding.
