1tsp nigella seeds (optional, for sprinkling on pie crust)
Method
Pre-heat your oven to 200c
In a large pan, gently cook onion in the oil until soft
Add the garlic & ginger and cook for another minute
Add in the balti paste and 150ml water and stir until reduced and thickened
Next add in the diced chicken and fry until sealed
Add in the tomatoes & red pepper and stir
Depending on the consistency, add water as necessary. You want a fairly saucy curry but not too wet that it wont go in a pie
Simmer uncovered until chicken is cooked through and sauce is desired consistency
Remove from the heat and chill. You want the curry to be cold before adding to the pie
While the curry is cooling, line your pie tin with butter
Roll out 1 sheet of puff pasty, enough to line the bottom and sides of the tin
Gently line the pie tin with the pasty, making sure its pressed in all around the bottom and comes up over the edges. Trim any excess
Blind bake the pastry - If you have baking beans, add them to the pan, if not, rice will work
Blind bake in the oven for 8-10 minutes to ensure the bottom of the pie gets a head start and doesn't go soggy when adding the curry
Remove from oven, discard the rice and add the curry, bringing it up to the top of the pastry
Brush some egg wash around the top of the part baked pastry
Roll out the other sheet of puff pastry and gently add over the top of the pie. You want it to the top of the filling and part baked pastry, not the top of the tin. Press around the edges slightly to ensure a seal with the part baked pastry
Use a knife to discard any excess pastry
Brush the top with egg wash then pierce all over with a fork
Finally, sprinkle with nigella seeds then bake in the oven for 25-30 minutes, until the pie looks nice and golden
