OMgawd ! I tried the roasted mushroom white sauce, so simple and so dang good ! I took a 8oz package of mushrooms roasted them with a touch of olive oil, then pureed them with 5 TBSP (as needed) heavy cream, Some raw red onion and a couple tablespoons fresh rosemary, touch salt and pepper. (There are no measurements do this to your taste) I’m telling you this is the best white sauce ! For toppings I tried blanced spinach, and pine nuts- FANTASTIC !
