- Why is the crust hard?
- Too thick or baked too long at low heat. This dough needs 'shock baking': very hot oven, short time.
- Can I use yeast?
- Original recipes usually don't, resulting in a cracker-like crust. Yeast makes it softer and more bread-like.
Flammkuchen (German Bacon and Onion Flatbread)
The 'Flame Cake' (Tarte Flambée) is a rustic gift from the Alsace region. Originally used to test oven temperature before baking bread: if the thin dough crisped in minutes, the oven was ready. The secret is the yeast-free, paper-thin dough and the combination of rich sour cream (or crème fraîche), sweet onions, and smoky bacon. Light, crispy, and addictive.

Instructions
1
✓
Measure flour and mix in salt. Add water and oil, knead quickly into a smooth, elastic dough.
Tip: Don't over-knead; just until combined, or it gets rubbery.
2
✓
Form a ball, coat lightly with oil, and rest at room temperature for 15-20 minutes.
Tip: Resting relaxes the gluten so you can roll it thin without it shrinking back.
3
✓
Preheat oven to max (480-500°F). Slice onions paper-thin (half-moons), dice bacon.
Tip: Onions should be translucent thin to cook fully in the short time.
4
✓
On a floured surface, roll dough into a very thin oval or rectangle (1-2 mm). Place on a parchment-lined baking sheet.
Tip: You should almost see through it! That's the key to crunch.
5
✓
Spread sour cream edge-to-edge. Lightly salt (bacon is salty!) and pepper generously.
Tip: The fat in sour cream protects the dough from drying out.
6
✓
Scatter onions and bacon evenly on top.
Tip: Rendering bacon fat will season the onions and cream.
7
✓
Bake for 10-12 minutes until edges are dark brown and crispy, and bacon is cooked.
Tip: Watch closely; thin dough burns fast!
8
✓
Serve immediately, piping hot, sliced on a board.
Tip: Wait for no one; it's best fresh.
