Whole Water Chestnuts (Can)
Preheat oven to 450 degrees. Leave water chestnuts in the can and drizzle them with a coating of soy sauce. If you don't want to use all of the chestnuts you can take some out and stick them in an air tight container and store them in the refrigerator. You want to let the water chestnuts soak in a little layer of the soy sauce for maybe ten minutes... giving them a little toss occasionally so they all get evenly coated.
Take each water chestnut and wrap it in a piece of bacon. I did this by setting it toward the center of the piece of bacon and pulling each corner up around it and securing on top with a toothpick. The bacon should stretch a little to fit.
Place the bacon wrapped water chestnuts on an ungreased cookie sheet and bake at 450 for approximately 20 minutes. You want to keep an eye on them towards the end and judge whether they're done or not by your desired level of crispiness for the bacon.
