An update on the previous post for leek and goats cheese tart. Do try this version. It was rather delicious using buttermilk in the filling which went very well with the watercress.

Tart base (see previous post)

2 onions, sliced finely
1 tablespoon rapeseed oil
1 clove garlic
Big handful fresh oregano, finely chopped
60g watercress
1 77g pack smoked diced pancetta
100ml double cream
175ml buttermilk
3 eggs (1 whole and 2 yolks)
25g cheese (parmesan, pecorino Romano, cheddar)
Spring onion to garnish

Pre heat the oven to 190 c
Sauté the onions and pancetta in the oil, grating in the clove of garlic and half the finely chopped oregano. Season well.
Put into a bowl and cool slightly before stirring in the watercress. Whisk the eggs, buttermilk and cream together. Season.
Stir the egg mixture into the filling mix, grate in half the cheese and add the rest of the oregano. Turn into the pastry case and top with the rest of the cheese.
Bake for 18 t0 20 minutes or until just set.
Leave to rest for a couple of minutes before serving. Delicious at room temperature as well.5BC8DC30-3FCA-4AA1-8E64-2EC46B143544
