In a medium sized mixing bowl, season the mushrooms with salt, pepper and vinegar and set aside while the olive oil is heating up.

In a medium sized pot, heat the olive oil with the dried red pepper flakes, lemon peel and bay leaf until it reached 150 F on a thermometer. Then pour the olive oil mixture over the mushrooms and cover the bowl with a plate or lid and let rest for 1 hour. The mushrooms will become soft and infused with all the flavor from the olive oil. Drain off most of the olive oil, reserving it for another use and serve the mushrooms on top of toast or as needed.
