The first evening it had a perfect bull’s-eye pattern of mold. Sixty hours later it had grown more (partial) rings of mold. Another forty-eight hours later it had grown still more partial rings, always separated by the same gap and all still roughly concentric. At that point it was getting pretty rotten, so I threw it away.

However, allicin is not stable and generates numerous smelly sulfur-containing compounds, hence its pungent smell. After ingestion, allicin and its breakdown products enter the bloodstream through the digestive system and are free to leave again in exhaled air or through perspiration. This is the first effect of garlic. In addition, the chemicals in garlic change the metabolism of the body and trigger degradation of fatty acids and cholesterol in the blood: this generates allyl methyl sulfide, dimethyl sulfide, and acetone.
