Alfredo? I make it---too easy: cream, parm cheese, butter, salt. I'm not a fan of it however. I like the red sauces better and my favorite is Target's house brand, plain. I'll add spices or garlic if I want, some meat or checken. I like it best because it is rich enough but doesn't have a really strong fake herb or spice taste so I can make it taste like I want it to taste with fresh ingredients (like leftover chicken or some herbs from the garden).
AND it is CHEAP!
