Mushroom pie & potato with goats' cheese

I received a comfort food cook book from my boy for my birthday, which is great because comfort food is the best kind! My first recipe was a delicious pie/tart using mushrooms and goats' cheese.

Ingredients:
200ml milk
150ml double cream
1 garlic clove
350g potatoes
50g butter
350g mushrooms (I used field and button as they were all that was left at the grocer)
100g goats' cheese
2 sheets frozen puff pastry
salt and pepper to taste
Thyme is a nice addition as well

Prior to starting, I preheated the oven to 200C. First I cut the potatoes into 2cm x 2cm cubes and placed them in a pot with the milk and cream, then brought this to the boil and simmered until the potatoes were cooked (about 15mins). While the potatoes were cooking, I cooked the mushrooms in the butter with thyme over a medium-high heat, cooking until all moisture had left the pan.
Once all above had cooked I laid the pastry out into a cooking dish, and filled it first with the potatoes, then with the mushrooms on top. I then put the cubed goats' cheese on the mushrooms and closed up the pastry. I brushed the top of the pastry with milk, scored it, then put it in the oven for 20mins - or until the pastry looks cooked enough.
Delicious!

Just as a note, I would probably use a different cheese next time - probably fontina. This is just my personal taste though and goats' cheese worked pretty well.
