Oat flour makes a crisp, rich crust – the perfect foil for a smooth pea filling and some cool probiotic labneh. The tart is easily digestible, but you could increase its probiotic value by adding a garlic clove and using the white of the onions.
Serves : 4
Ingredients Oat Crust:
70g oat flour (or porridge oats, ground)
70g buckwheat flour
70g ground linseed
2 pinches of sea salt
70g cold salted butter, diced
80-100g live Greek-style yogurt
Pea and basil filling:
225g frozen peas
3 large organic eggs
150ml double cream
Finely grated zest of 1 lemon, plus juice of 1/2 lemon
Large handful of basil, plus extra to dress
3 pinches of sea salt
4 spring onions, green parts only, sliced
Olive oil, for drizzling
Freshly ground black pepper
Step One : For the crust, put both flours, the linseed and salt into a bowl, rub in the butter until it resembles coarse breadcrumbs, and use a knife to stir in half the yogurt. Add the remaining yogurt in teaspoons, until the mixture starts to clump, then gather into a ball and knead till smooth. Form into a disc, then wrap and chill for 20-30 minutes.
Step Two : Preheat the oven to 200oC / 390oF / Gas Mark 6 and line the base of a 23cm loose-based tart tin with baking parchment.
Step Three : Lay a sheet of clingfilm on the worktop, place the pastry on it and cover with clingfilm. Roll into a circle to line the tin, peel off the top layer of clingfilm, and ease the pastry into the corners before removing the clingfilm and trimming the top edge. Chill for at least half an hour.
Step Four : Line the tart case with parchment, fill with baking beans and bake for 15 minutes, then remove the parchment and beans and bake for 5 minutes. Set aside. Turn the oven down to 180oC / 390oF / Gas Mark 4.
Step Five : To make the filling, blanch the peas in boiling water until just cooked. Refresh in cold water, then drain and reserve 25g. Put the remaining peas into a blender with the eggs, cream, lemon zest and juice, basil and salt. Blend and pour into the case, then scatter over the onions and reserved peas.
Step Six : Bake for 30 minutes, until set. Put side till just warm, then scatter with labneh and basil and drizzle over the olive oil. Season with black pepper and serve.
