To seal a wooden bowl, you can use a food-safe wood sealant or finish such as mineral oil, beeswax, or a combination of both. First, sand the bowl to smooth out any rough spots and then wipe it clean. Next, apply a generous amount of the wood sealant or finish to the entire surface of the bowl, making sure to cover all the wood. Allow it to dry completely before using the bowl for food. This will help protect the wood from moisture and food stains, and also give it a nice polished look. **
