- Turn a fry pan onto a medium heat
- Put the butter into the fry pan
- Sauté the onions and garlic in the butter
- Add the mushrooms and allow the mushroom and onion to completely soften
- Add the cream and keep on a medium heat for approximately 5 minutes. This will start the reducing process.
- Reduce to a low heat and cover and simmer for 15-20 minutes (or until the desired mushroom taste has been achieved - the sauce should be grey before you consider taking it off the heat). You may need to take the lid off and reduce the sauce for another 5 minutes if it is too runny.
- Add salt and pepper to taste
