Note: All measurements are guesses, I am the zen master of sloppy joes (probably the only cooking thing I have really mastered) and just add "enough" of each at each appropriate phase. My measurement guesses should be close and you can go conservative on certain parts until you get more experience. This is really a classic, delicious recipe that is worth mastering.

Brown the hamburger, breaking it up with a spatula into small pieces, drain the grease, then immediately after draining, turn down the heat a bit and squirt in a lot of Heinz ketchup. You CAN use too much, but squirt a bunch in, stir it up and then add a fair bit of water, maybe 2/3 cup. Stir it around and see if it looks too brown or red. If it looks mostly brown and hamburger colored, you need more ketchup. If it looks RED, you have gone crazy and put in too much ketchup, you suck. It should look orangeish-brown. Until you master the recipe you can go light on the ketchup and dip the sloppy joes in ketchup, but optimally you should cook it for best flavor with just the right amount of ketchup. Don't worry, this just takes experimentation and experience.

Add 3-4 healthy dashes of worcestershire sauce and the brown sugar. Both are critical for flavor and you may want slightly less or more brown sugar. You can add more brown sugar, but be careful, its easy too go to far and end up with overly sweet sloppy joes. Its really just an accent flavor and a counterbalance to the mustard and worcs sauce. On the other hand, its hard to overdo the worcs sauce, lots of it usually works very well Add a little squirt of mustard, not very much at all really.

Mix it all in and add more water, it should look way too watery at this phase. If it looks like just enough water, you don't have nearly enough; be bold and add more. The reason for this is that you are going to simmer it for about 15 minutes, and the water will cook in and help give the hamburger the wonderful texture it needs for optimal sloppyness. Lower the heat a bit and simmer.

After its simmered a while, sprinkle in the cornstarch and mix that in thoroughly (also possibly add a little more water at this point), lower the heat a bit more and simmer for another 5-10 minutes, stirring occasionally. The cornstarch helps it all solidify up into an awesome texture that is properly gooey but still sloppy. You can add more/less cornstarch per your preferred texture. Toast the hamburger buns lightly in a toaster oven @350 degrees. Now for you sloppy joe challeneged folks, the last step is to put the sloppy joe material in the toasted buns and start eating them
