English pie recipe

Hi,
While starting watching The great british bake of I've been tempted to make some english pie myself, but then totally vegan :)
Here you have my recipe :) For 2 ;)

For the pie :
- Flour 200gr
- Butter (vegan) 100gr
- Ice cold water
- Pinch of salt

For the stuffing :
- Mushrooms
- Spinach

- Soy milk
- Salt
- Pepper
- Butter
- Flour

I started to make the stuffing first cause everything needs to be cold before putting the pie together to have a good bake.
First wash and cook your spinach, then do the same with your mushrooms.
I make my saus to bind everything like this: put some butter in a pan then ad a spoon of flour to it and some salt and pepper. Now put the stove on under your pot and whisk all this together, when it all start to stick together you put some soy milk to the mix but keep whisking. Put soy milk and whisk till it look like a good texture. Now put your vegetables in the saus, make sure to get most of the water out of your spinach. Mix this all together and if necessary put some more salt and pepper.
Now you can put this aside to cool down.

For the pie put the flour in a bowl and ad the butter to it. Wash your hands cause you're going in :)
Rub the butter into the flour gently if it's all mixing together you can start by adding 4 spoons of the ice-cold water in. Keep doing that till you have a good texture. Roll the dough in a ball and put it in the bowl with a plastic foil over it and put it for 30 min or longer in the fridge to cool.

Now get some flour on your counter top and roll out the dough till it's half a cm.
Make sure to butter up your cooking form you're going to put this in and put some flour in it to, so it doesn't stick after.
Now put in your stuffing.
Then roll out the rest of your dough to use as the top.
Put it over to close your pie but cut a whole in the middle of it to let the air out.
Now brush on some water over the top to make a nice crust.

Put it in the oven for 40min on 180°C. Till it's golden brown.

Watch out it will be hot when you get it out so let it cool for a few minutes before eating it :)
Enjoy your pie :)
( Of course you can fill your pie with everything you want, if your not vegan you can of course put some cheese in it, and if you eat meat go ahead and enjoy )

Love,
Sarah
