Smoked salmon pesto tart

Method

1. Preheat the oven to 200°C/fan180°C/gas 6. Unroll the pastry onto a baking sheet, brush with the beaten egg and bake for 20 minutes or until risen, crisp and golden.
2. Meanwhile make the pesto. Whizz the garlic and pine nuts in a food processor (or pound in a pestle and mortar). Add the parsley and dill, then pulse (or pound) again until finely chopped. Remove to a bowl, add the Parmesan, then drizzle over the oil, whisking, until you have a spoonable consistency. Season to taste and squeeze over a little juice from the unsliced lemon half.
3. Mix the onion, lemon slices and capers. Dress with the rest of the juice from the lemon half, a drizzle of olive oil and a little salt.
4. Top the cooked pastry with dollops of the crème fraîche, the smoked salmon and the onion mixture. Return to the oven for 5 minutes to warm through. Drizzle with the pesto, garnish with the dill and serve with a crisp winter leaf salad.
