The tomato sounds good. Can you please post your scratch Alfredo recipe?
My Alfredo recipe is equal parts cheese and butter. With that as the basic concept, variations can be made- saute garlic in the butter before adding cheese, add a pinch of nutmeg (I don’t like it), and / or herbs. A very good variation is adding a good squeeze or orange. I will also add cream to make it thinner at times, too. I tried bottled once. It was awful. It tasted like wheat. Anyway, that’s my version.
