Buckwheat Crackers with Smoked Fish

• 3 cups all-purpose flour, plus more for dusting
• 1/4 cup buckwheat flour
• 1 teaspoon fine salt
• 1 stick cold unsalted butter, cut into small pieces
• 1/2 cup plus 2 tablespoons ice water
• 1 large egg, beaten
• Sea salt flakes, for sprinkling
• 1 cup creme fraiche
• 1 tablespoon fresh lemon juice
• 1/2 teaspoon freshly ground black pepper
• 1/2 pound thinly sliced smoked salmon
• 1/2 pound smoked mackerel fillets, skinned and broken into pieces
• 1/4 pound smoked shrimp
• Sliced onions, for serving

1. In a large bowl, mix the all-purpose and buckwheat flours with the fine salt.
2. Using a pastry cutter or 2 knives, cut in the butter until it resembles small peas.
3. Sprinkle with the ice water and press gently with your hands to form a dough.
4. Flatten the dough into an 8-by-6-inch rectangle, wrap in plastic and refrigerate for 1 hour.
5. Preheat the oven to 400.
6. Line a large rimmed baking sheet with parchment paper.
7. Cut the dough into 4 equal rectangles.
8. Working with 1 rectangle at a time and keeping the rest refrigerated, roll out the dough on a lightly floured surface to a 10-by-12-inch rectangle, about 1/16 inch thick.
9. Transfer to the prepared baking sheet.
10. Brush with the beaten egg and sprinkle with sea salt.
11. Let stand for 3 minutes to let the egg wash dry.
12. With a pastry wheel, cut the rectangle into 2-inch squares.
13. Separate the squares, leaving about 1/2 inch between them.
14. Top the squares with another sheet of parchment paper and another baking sheet.
15. Bake for 25 minutes, until the crackers are golden brown.
16. Transfer to a rack to cool.
17. Repeat with the remaining dough, egg wash and salt.
18. In a small bowl, mix the creme fraiche, lemon juice and pepper.
19. Arrange the smoked fish, shrimp and onions on a platter.
20. Serve with the crackers and creme fraiche.
