Answer: Cornstarch-pressed bricks are made by putting cornstarch in a hydraulic press and compressing and heating it to form a solid brick. Cornstarch can be pressed by machine or by hand. Here are some steps to make cornstarch chunks:
1. Put cornstarch and any seasonings in the box.
2. Press well, putting all the strength you can into making a block with the cornstarch. The goal here is to remove air and make a solid block.
3. With the brick formed, carefully transfer it to the aluminum foil and wrap it well. It will look like a giant candy bar.
