Preparation steps 1 Preheat the oven to 200 °C. 2 Line a large baking tray with baking paper. 3 Finely slice the onion. 4 Mince the garlic. 5 Heat half the olive oil in a large frying pan. 6 Soften the onion for 4 min over medium heat without browning it. 7 Add the garlic and cook for 30 seconds until fragrant. 8 Add the spinach a handful at a time and let it wilt for 3 to 4 min, stirring. 9 Tip the spinach into a colander and leave it to cool for 10 min. 10 Squeeze the spinach firmly between your hands to press out all the water. 11 Roughly chop the squeezed spinach. 12 Finely chop the dill. 13 Crumble the feta into a mixing bowl. 14 Add the ricotta, one of the eggs, the dill and the spinach to the feta. 15 Season the filling with nutmeg and pepper, without salt: the feta is salty enough. 16 Mix the filling until evenly combined. 17 Unroll the puff pastry sheets and cut each one lengthways into two strips. 18 Spread the filling in a log along each strip, 1 cm from the edge. 19 Roll each strip over the filling into a long tube. 20 Pinch the seam firmly to seal it. 21 Lay the tubes end to end, seam side down, and pinch the joins together. 22 Coil the long tube into a loose spiral on the tray. 23 Pinch the centre end into a point to form the tail. 24 Flatten the outer end slightly and round it off to form the head. 25 Beat the second egg with a pinch of salt. 26 Brush the whole snake with the egg wash. 27 Score scales in a criss-cross pattern along the back with the tip of a knife, without piercing the pastry. 28 Sprinkle with the sesame seeds. 29 Press two pieces of black olive into the head for the eyes. 30 Bake for 30 to 35 min until the snake is puffed and deep golden. 31 Meanwhile, cut a thin strip of red pepper. 32 Notch one end of the strip into a fork to make the tongue. 33 Squeeze the lemon. 34 Dress the rocket with the lemon juice, the remaining olive oil, salt and pepper. 35 Leave the snake to rest for 10 min on the tray. 36 Slide the pepper tongue under the head. 37 Serve the whole snake in the middle of the table, surrounded by the rocket, and slice it at the table.
