But as usual with cooking I'd recommend a slight variation to it.
What you need
- 1 onion
- 1-2 table spoons of flour
- 2 table spoons of olive oil
- salt, pepper, thyme (best if fresh)
- 2 sweet potatoes
- package of porcini mushrooms
- 400 ml water
- 200 ml white wine (dry)
- creme fraiche
- Sauce pan
- quiche form
How you do it
- put the dried mushrooms in a bowl and cover with white wine. 200ml should be enough
- let rest for at least 30min
- after 30min, put 400ml of water in a sauce pan and bring to the boil
- pour the dried mushrooms with the white wine into the sauce pan and cook for 5 min
- take sauce pan off the cooker and pour all of its content back into the bowl
- peal and chop the onion
- clean & dry the sauce pan and put 1 table spoon of olive oil in it
- heat until the oil is hot pour the chopped onions in it.
- Add some salt & pepper.
- you need to cook the onions for 12-13 min. Stir while they're cooking.
- The onions should be golden brown.
- Then put the 1-2 table spoons of flour in the sauce pan. Stir for ca 3 min
- slowly pour the mushroom/water/gravy mix in it while stirring. Do this step by step - so that at each step the sauce has a chance to thicken.
- when you poured all of the mushroom/water/whine mix in - continue cooking and stirring for ca 5min.
- Put the oven on 200 C or gas mark 6
- peal the sweat potatoes and cut in 5mm chunks
- put the cut potato pieces in the form
- sprinkle salt, thyme, pepper and a bit of olive oil over them
- put in the pre-heated oven and let bake for ca 30min
Voila: get the potatoes out of the oven and place on a plate. Pour some of the gravy over it and a tea spoon of creme fraiche on the side.
