This one has a bit of urban legend to it. The main components of semen are citric acid (think lemons), proteins and their building blocks, sugars, fats, a few minerals and sperm. Many studies have tried to identify foods that change the taste of semen, but none are 100% conclusive. However, some folks say that eating foods that are naturally high in fructose (like mangoes and pineapple) will make semen taste sweeter, while foods high in sulfur (like brussels sprouts, cauliflower and broccoli) make semen taste bitter. Other things that may negatively impact the taste include a diet that is high in meats and fish, alcohol, smoking and caffeine. Again, none of this is backed by science but plenty of folks have a lot to say about it.

Keep in mind that whatever the effect of food on the taste and smell of semen, the changes will be brief. Foods and liquids are processed relatively quickly, so eating a bunch of asparagus now really won’t have much of an impact in a couple of days.
