How do you remove sugar taste in food?

For liquidy foods such as soup, it is really quite simple. Toss a couple of pieces of cubed potato in. Potato is really good at absorbing salts. If your mixture is very clear, the potato may cloud it though. Make sure you chunk it large enough you can easily fish it back out when you are ready.

I have also found that (when appropriate to the dish); Adding some (red) wine will

minimize the salty taste and boost the natural flavors of the dish.
