Definitely! The best way to go about this is to first remove the saucepan from the heat. Do this immediately when you see curdling starting to occur. Cool it down as quickly as possible by lowering it into an ice bath or simply transferring the sauce to a different pan or bowl.  Mix in a spoonful or two of lemon juice, cream, or white wine. Pick one and stick with it. Adding more than one of these options will negatively affect the flavor. Whisk thoroughly to remove clumps.
