Heat oil in a pan over medium heat. Add garlic and spinach and cook until wilted. Set the wilted spinach on kitchen towel to soak up any excess liquid.
Step 3 : Assemble the ingredients
Roll out the pastry on a floured surface.
Place the raw salmon in the center of the pastry.
Layer the wilted spinach on top of the fish and sprinkle with pepper.
Layer the smoked salmon evenly over the spinach.
Bring the edges of the pastry over the fish and seal thoroughly by pinching the edges together. Repeat at each end.
Trim away any leftover pastry.
Step 4 : Bake
Brush the pastry all over with beaten egg and sprinkle with cumin seeds.
Place the pastry on a baking tray and bake in the hot oven for 25 minutes, or until nicely golden.
