Household Uses for Starch
Sprinkle the cutting board and rolling pin with tasteless powdered Corn Starch before rolling out the dough.
Thicken gravy -
Corn starch has twice the thickening power of flour. When a gravy, sauce, soup, or stew recipe calls for flour, use half as much corn starch to thicken. One tablespoon of corn starch equals two tablespoons flour.

After the water boils, pour the cornstarch mixture into the boiling water and stir for a minute or so. The liquid will be clear or slightly cloudy. Remove the saucepan from the heat and let cool to room temperature, stirring occasionally. Fill a spray bottle and use as you would any starch. Be sure to shake vigorously before each use. Throw away after 3 to 4 days.

But what if you don't have access to cornstarch? If you have access to potatoes, you can make your own starch. First, it is useful to know how to store potatoes to preserve their starch content.
Freezing potatoes or storing them in the refrigerator will cause some of the potato starch to be converted to sugar and reduce the starch content. If potatoes that were previously frozen are used to make starch, you will find that the high sugar content will likely caramelize when heated. If used in a laundry application on white cloth, you may find that some staining results as the caramelized sugar will stain the garment. You will find that refrigerated potatoes darken when cooked due to the increased sugar content.
One way to determine the starch content of a potato is to rub two cut surfaces of a potato together. If a foam develops, it indicates a high starch content, and usually the two cut surfaces cling together. If the potato has a low starch content, the cut surface will be clean and moist and the two cut surfaces do not bond at all.
HOW TO MAKE POTATO STARCH
You will need:
* 1 washed potato, peeled and diced or grated
* 1 cup water
* blender OR mortar and pestle
* Coffee filter OR clean cloth OR fine sieve
Place water and potato into the blender and turn it on high for 1 to 2 minutes.
If using a mortar and pestle, add both water and potato pieces to the mortar and process until well incorporated.
Place the resulting mush into the coffee filter (or cheese cloth or clean cotton cloth) and reserve the cloudy liquid. You can filter the water through another clean cloth if you like. Allow this to set for a while. Once some sediment has settled at the bottom, carefully pour the liquid off into a storage container, allowing the sediment to remain in the bottom of the original container. This can be done more than once, if you prefer. The filtered, cloudy water is liquid starch.
Drying the mixture is not completely necessary, but if you plan on storing it for a while, spread it out on wax paper in a sunny area for it to dry. Or you can place it on parchment paper on a tray in a very low heat oven -- in most cases leaving the light on with the door ajar will be adequate -- overnight and until the film has dried to a powder.
UPDATE ON MAKING YOUR OWN PLASTIC:
Whether or not you are willing to tackle the project of making your own bioplastic, some businesses have decided that it is a marketable idea.
MLB gives green light to recycling efforts (3/12/2008)
[Major League Ballpark beverages] may be served in a container with the look and feel of a plastic cup but instead made of biodegradable corn starch.
Using corn starch cups, increasing recycling and installing solar panels and possibly wind turbines at ballparks are among the measures teams will consider as part of a major league-wide effort to reduce baseball's carbon footprint.

FIND A RETAILER
Amazingly, you can type the words "cornstarch cups" into your internet search engine and find a list of retailers that sell compostable cups, bowls, plates, lids, knives, forks and spoons. Some sites call them 'corn cups.' However, like all mass produced food items, you'll have to watch the ingredient list. Likely there are several chemical additives to ensure uniformity of the product. Shop carefully if you decide to purchase.
