Directions
<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Preheat your oven to 190°C (375°F) and line a large baking sheet with parchment paper. If using Greek yogurt, place it in a fine-mesh strainer lined with cheesecloth and let it drain for about 30 minutes to remove excess moisture. This will prevent your pastries from becoming soggy during baking.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>Clean the leeks thoroughly by cutting them in half lengthwise and rinsing between the layers to remove any grit. Slice them thinly into half-moons. Heat 3 tablespoons of olive oil in a large skillet over medium heat. Add the leeks and cook for 8-10 minutes until softened but not browned, stirring occasionally.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>Add the minced garlic to the leeks and sauté for another minute until fragrant. Stir in the cumin, coriander, paprika, and turmeric. Cook for 30 seconds to bloom the spices, releasing their aromatic oils. Remove from heat and allow the mixture to cool completely (about 15 minutes). The cooling process is crucial as hot filling will make the phyllo dough soggy.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>In a large bowl, combine the cooled leek mixture with the drained yogurt, crumbled feta (if using), chopped dill, mint, salt, and pepper. Mix gently until well combined. Taste and adjust seasoning if necessary – the filling should be well-flavored as the phyllo itself is neutral.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Carefully unwrap your phyllo dough and cover it with a slightly damp kitchen towel to prevent it from drying out. Working with one sheet at a time (keeping the rest covered), place a sheet on a clean work surface and brush lightly with melted butter. The thin application of fat creates steam pockets during baking, resulting in those distinctive flaky layers.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>Place a second sheet of phyllo on top of the first and brush with butter again. Cut the stacked sheets into 4 equal strips lengthwise. Place about 2 tablespoons of the leek filling at the bottom of each strip. Fold the right corner over the filling to create a triangle, then continue folding upward in a triangle pattern (like folding a flag) until you reach the end of the strip. Seal the end with a little butter if needed.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Place the triangles seam-side down on the prepared baking sheet. Brush each pastry generously with beaten egg and sprinkle with sesame or nigella seeds. The egg wash will give your pastries that beautiful golden-brown shine while helping to seal the edges.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>Bake in the preheated oven for 20-25 minutes, or until the pastries are crisp and golden brown. Watch them carefully after the 15-minute mark as phyllo can go from perfectly golden to burnt quite quickly. The layers should be visibly crisp and make a subtle crackling sound when gently pressed.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>Allow the pastries to cool on the baking sheet for 5 minutes before transferring to a wire rack. This brief resting period allows the filling to set slightly and prevents the pastries from becoming soggy. Serve warm or at room temperature, perhaps with an extra dollop of yogurt on the side. These pastries are best enjoyed fresh but can be stored in an airtight container in the refrigerator for up to 3 days and reheated in a 160°C (320°F) oven for 5-7 minutes to restore crispness.</li></ol>
