Fish pie

My wife bought this pack of short crust pastry from TESCO (note it was "light"). She wanted me to make a fish pie. So what I did was defrosted a pack of smoked mackerel (300g), and 200g of cooked prawns. Whilst this was going on I heated a tablespoon of coconut oil in a heavy pan. To this I added two finely diced carrots, potatoes, one courgette, one diced onion and three cloves of garlic. I sweated this off until it picked up a nice caremalised colour. I added 200 ml of water-stock can be used. I seasoned with salt and pepper and basil. Then added 250ml of cream. The mixture was cooled and was then put into an oven dish and I rolled the pastry over it. This was milk washed and a vent was placed in middle. Point of note I doubled over the excess pastry which on reflection should not have done. This was then popped into a pre heated oven and cooked for 25 minutes at 180 oC and I rotated it once. Et voila my fish pie was ready to feed four. It tasted great!!
