Notes

🌿 A Taste of Finnish Tradition
Perunarieska (pronounced peh-roo-nah-ree-eh-skah) has its roots deep in the rural kitchens of Finland, where practicality and resourcefulness reign supreme. Historically, this type of flatbread was born out of necessity — a way to use up leftover mashed potatoes while creating something hearty and filling. Unlike sourdough or yeasted loaves, rieska requires no rising time, making it the bread of choice for busy households and weeknight meals. Traditionally, this flatbread is baked in a wood-fired oven and served warm with a thick layer of butter, sometimes sprinkled with a pinch of salt or fresh herbs. While modern ovens do the trick just fine today, the soul of the bread remains: simple, satisfying, and full of Finnish character.🛠️ Tools & Equipment

👩🍳 How to Make Finnish Potato Flatbread
1. Preheat and Prep
Set your oven to 475°F (245°C). Line one or two baking trays with parchment paper.2. Mix Dry Ingredients
In a large bowl, combine the mashed potatoes, flour, and salt. Mix until the texture is sandy and even — a pastry cutter works great for this step.3. Add the Egg
Crack in the egg and mix with a wooden spoon until the dough becomes soft and smooth.4. Portion and Shape
Turn the dough onto a lightly floured surface. Divide it evenly using a bench scraper or knife. Choose your size:- 10 small flatbreads (~45–50g each)
- 5 larger flatbreads (~90–100g each)
5. Prick and Bake
Place the flatbreads onto the lined trays. Use a fork to prick each disk in neat columns — this prevents puffing.- Bake small flatbreads: 8–12 minutes
-
Bake large flatbreads: 12–15 minutes
…or until they turn a light golden brown.
6. Serve Warm
Let them cool on the tray for 5 minutes. Serve warm with a generous pat of butter — or get fancy with garlic butter or fresh dill for a Nordic twist! 🧈🌿🔄 Variations & Substitutions
- 💪 For a whole grain version: Replace up to 50% of the flour with whole wheat, barley, or rye flour for a deeper, nuttier flavor. Keep in mind that whole grain flours absorb more moisture, so you may need to tweak quantities.
- 🍠 Curious about sweet potatoes? You can experiment with mashed sweet potatoes instead of regular ones — though the texture might change, and you’ll likely need to adjust the flour amount. (Test in progress! Stay tuned for updates.)
