I bought brussels sprouts (on the stalk) at the farmers market and just happened to get a quite buggy one. I took the sprouts off and soaked them to get rid of grit and the bugs, but I've changed the water 5 times now and I'm still getting bugs in the water. Is there a trick to make this go faster? Hot water? Vinegar? Just forge ahead and cook them and convince myself I'm eating black pepper?
