It may seem like a strange question, but for serious pasta lovers, or tomato sauce lovers, it’s taken pretty seriously.
Whether it’s just an old wives tale or not, there are many folks who say there is scientific truth to the fact that a metal spoon will impart a metallic taste to the sauce due to the acidity in the tomatoes coming into contact with it. Wood is the preferred material to use when making tomato sauce because of its rounded edges and non-reaction with the tomatoes.
I say go for the wood spoon, if for no other reason than to taste that wonderful sauce with the rounded edges of the spoon without interference from cold metal or stainless steel and definitely not plastic or silicone. Besides, wooden spoons are pretty to have in your repertoire of kitchen utensils, ever-useful and something in which every home cook should have at least more than a few.
