Why does your popped popcorn sometimes taste like it is a little moldy?

There are a few reasons why your popped popcorn might taste like it is a little moldy.

1. The popcorn kernels were not stored properly. Popcorn kernels are susceptible to mold growth if they are not stored in a cool, dry place. If you store your popcorn kernels in a warm or humid environment, they may become moldy and develop a musty or sour taste.

2. The popcorn was popped in dirty oil. If you use oil that has been used to pop other foods, it can transfer the flavors of those foods to the popcorn. This can result in popcorn that tastes like something other than popcorn, including mold.

3. The popcorn was not popped long enough. If you do not pop the popcorn long enough, the kernels will not fully expand and will retain some of their moisture. This moisture can provide an environment for mold to grow, resulting in popcorn that tastes moldy.

4. The popcorn was left out in the open air for too long. If you leave popcorn out in the open air for too long, it will absorb moisture from the air and become stale. Stale popcorn can develop a musty or sour taste, which can be similar to the taste of mold.

If you are concerned about the taste of your popped popcorn, it is best to discard it and make a fresh batch. To avoid mold growth, be sure to store your popcorn kernels in a cool, dry place and pop them in fresh oil.
