Glaze the pan with the wine, add butter to the pan, and the mushrooms. Add the lemon and zest. Cook the mushrooms for a few minutes and then add in the chicken stock. Add the rue mixture for thickening and keep adding as much chicken stock as necessary until you have the desired thickness. Add in some half and half. I eyeball everything! Sorry guys, it’s how If experiment and learn! Haha! Just get it to the desired thickness you want by adding a little at a time. Make it fun! Salt and pepper to your liking!
