If you don’t have any vodka on hand, you can swap in some white wine in a pinch. The finished sauce won’t have quite the same bite to it but it will still be tasty.  You can also leave the alcohol out entirely and still have a creamy and delicious tomato sauce. If you choose to omit the alcohol, you may want to swirl in a tablespoon of balsamic vinegar when the sauce is finished to give it that extra layer of flavor.
