Featured Question

Last year I made sauerkraut according to directions in a Kerr Canning Book. It was placed in a warm sun porch to ferment. I used a plate with a weight on top to keep the kraut under the brine. In 2 weeks it was beautiful and tasted good. Thinking I needed to let it go longer, I let it continue fermenting. It got moldy quickly and smelled like yeast. I disposed of it. I don't remember how I washed it out, but it continued to have mold growing inside the crock. How do I clean the crock to keep from having the spores grow mold/yeast in a new batch of kraut? I've read about people heating crocks in the oven. This would not be possible.
