 You will need

  • Bushel of corn
  • Garlic press or mechanical press
  • Strainer
  • Bucket


  1. First of all, we should press the corn kernels. Before pressing place corn in warm water for 12-24 hours. They will become soft and it will be much easier to press them. After that take them from water and press using a mechanical press or a garlic press. The procedure is the same: we will turn corn kernels into pulp. The pulp is slushy and watery. It is what we need. Press all the corn into a bucket.
  2. Now you have a liquid with some solid parts of corn. You need to strain the liquid. Use a strainer and remove all floating particles from the liquid. You receive the clean liquid.
  3. The next step of how to make corn oil is to wait for several days. Water in the liquid will evaporate. As water and oil have different densities they won’t mix. Let water evaporate by itself. You may just speed up the process by dividing the liquid into several bowls and putting them in the sun. The more area of evaporation will be the quicker you will make corn oil. After several days water will evaporate and you will see a yellow residue – corn oil. Pour it into a dark glass bottle not to go bad and label with the date of manufacturing.

    Seems to me that if you have the liquid from pressed corn and it has any particles from the corn in it, and you set it in the sun, you are going to have rancid liquid on your hands.
