The bitter taste of wild leek flower sauce may be due to the following reasons:

1. The wild leek flower itself has deteriorated.

2. During the production process, the heat was not controlled properly, resulting in the wild leek sauce being overcooked or mushy, resulting in a bitter taste.

3. The salt content in wild leek flower sauce is too high, resulting in a bitter taste.

In order to avoid these problems, it is recommended to use fresh chive flowers when making wild leek flower sauce, and control the heat to avoid overcooking or burning the ingredients. In addition, you can add appropriate amounts of millet chili and apple cider vinegar to improve the taste and neutralize the salty and bitter taste.
