My brother requested a recipe with blueberries, and so I flipped through the book and picked out this pie. The English name for kermaviili-musikkapiiras is “blueberry sour cream pie.” In Finland, it’s made with a special product called kermaviili. Ojakangas describes viili as “a yogurtlike clabbered milk that is much more delicious (to a Finn) than yogurt.” From what I can gather, it’s a bit like sour cream or crème fraîche. As a substitute, she suggests adding lemon juice to heavy cream, which is what I did, but I can’t help but wonder what this pie tastes like when made with actual viili.

The recipe is a rather simple one, with a pleasant (if not amazing) outcome. The pie is tasty, but it’s probably my least favorite of the pies I’ve baked from this book so far. I made a few modifications to the recipe as I went along, as I often do. This time, as I was preparing the cream filling, I spent some extra time whipping it up so that it would thicken a little bit. Ojakangas doesn’t specify how long the filling should be mixed for, and she definitely doesn’t instruct you to whip the filling, but f I hadn’t done this, the blueberries would have sunk right to the bottom and I expect it wouldn’t have set as it baked, either.

The pie looked quite pretty before it went into the oven – much prettier than it looked coming out. But the berries were soft and warm and gooey and the cream filling was tasty and the crust was buttery. It may not be my favorite pie, but it’s hard to go wrong with that, right?
