For the lemon yogurt whip: In a stand mixer fitted with a whisk attachment, beat the heavy cream and yogurt to soft peaks. Add the powdered sugar, vanilla and lemon zest and continue beating until stiff peaks. Refrigerate until ready to use.
For the flatbread: In a large bowl, whisk together the flour, baking powder, sugar, yeast and salt. In a medium bowl, whisk together the water, yogurt, vanilla and almond extracts and stir very well to get rid of any lumps. Pour the wet ingredients into the dry and stir until combined. Cover with plastic wrap or a towel and let it sit at room temperature until doubled in size and bubbly, 1 to 2 hours or refrigerated overnight.
Preheat the oven to 200 degrees F. Line a baking sheet with a clean kitchen towel or a layer of paper towels and stick it in the oven to hold cooked flatbread.
Heat a large skillet over medium heat and melt enough butter for a thin coating on the bottom of the pan. Pour in about 1/2 cup of batter and cook until the bottom is browned and starting to crisp and the bubbles on the top have released and batter has set. Don't flip it! Transfer to the baking sheet in the oven with a metal spatula. Repeat with remaining batter, adding more butter to the pan in between batches.
Warm some honey over medium heat or in the microwave. To serve, top a flatbread with the yogurt whip, a drizzle of warm honey, a sprinkle of pistachios, and fruit, if using. Enjoy!
