Wheat Starch - 500g

This powder starch can be cooked into a paste. 

Preparation Method:  Measure out 1 part starch and 4-5 parts water.  Mix a small amount of water into the starch, turning it into a slurry, breaking down any lumps.  Let sit for a few minutes.  Combine the remaining water and slurry into a double boiler set up.  Heat and stir the mixture until it turns translucent.  Continue to cook for another 5-10 minutes.  Remove and allow to cool to room temperature.  Store in a clean container.  Refrigerating the paste will extend its shelf life.  Discard when the paste smells sour or there is signs of mold.  Prior to use, force through a sieve to remove any lumps.  Can be thinned with water.

Alternative Microwave Method:  Prepare mixture as above, but place in a tall microwave save container.  Initially microwave for one minute.  Stir and continue to cook for another 30 seconds.  Repeat the cycle until the mixture turns translucent.
