Step 1
Start by melting the butter together with the olive oil in a skillet over medium heat. Once the butter is melted, add the mushrooms and fresh basil, cooking them until the mushrooms are warmed through. Pour in the rum and sherry, letting the mixture cook a bit longer until the mushrooms become tender. Next, stir in the lemon juice, sour cream, and Parmesan cheese, allowing everything to simmer gently until it’s nicely heated. Taste and add a pinch of salt before serving.
