The black bug on the broccoli looks really disgusting. If you can't get rid of it, you can't eat it anymore. When I do this job, I usually break broccoli. Soak in light salt water for half an hour. Add baking soda to the salt water. Soak for half an hour, then take it out and rinse it with clear water. Then put it in boiling water. Take it out after five minutes and rinse it clean. So there are no black bugs. The key is to soak broccoli and add baking soda to light salt water. .
