When choosing a sourdough starter kit, it's easy to overlook one of the most crucial components: the right mixing bowls. A good set of non-reactive mixing bowls is essential for creating and maintaining your wild yeast culture. Look for bowls made from materials like glass, ceramic, or stainless steel, which won't leach chemicals into your dough and can withstand the acidity of sourdough fermentation. A typical starter kit usually includes a glass or plastic container with a wide mouth, a measuring cup, and sometimes a wooden spoon or spatula. However, if you're serious about developing a robust sourdough culture, consider investing in a few additional non-reactive bowls to use during the proofing process. This will allow you to scale up your recipe and experiment with different techniques without worrying about contamination or flavor transfer.
