Making your own cooking oils means that you control the ingredients that go into your food, the  edible oil production at home is your good choice. Oils produced with cold press methods and little or no filtering have more flavor and healthier fats. Home production requires considerable effort, but you’re rewarded at the end with oil you can feed to your family without guilt, and the byproducts from making the oil are a nutritious feed for farm animals. Edible oils can be made from all kinds of seeds, nuts and even the most famous fruit for oil, the olive.

•  •Grind the hulled seeds or nuts with the meat grinder to a coarse texture. You may be able to see oil at this stage.
• •Every type of oil is a different color and taste. Drill holes into the PVC pipe evenly all around and from top to bottom. These will allow the oil to escape while pressing. Clean the pipe and make sure that no plastic bits cling to the holes.
• •Affix the jack to the counter with the clamps. Directly below it, place the metal plate on its pedestal inside a metal bowl. You will need a partner to hold this still while the PVC pipe is filled with the oil mash made by grinding the seeds. Pack the mash in tightly, as the friction will keep the pipe in place until the pressure is put on it. Place the second plate on top of the mash and lower the jack into position. There will be enough force at this point to let go of it.
  
  •Turn on the jack to its lowest setting. Allow it to press for about a half hour. Oil will run out of the holes and fall into the bowl below. When this step is completed, have your partner hold the pipe and pedestal while you release the jack. Remove the apparatus and cover the oil.•Allow the oil to settle overnight. You will see a great difference in clarity in the morning. If you plan to cook with the oil, use the coffee filters to remove the impurities or they will burn during cooking. For other uses, the oil may remain unfiltered. Place the oil into an opaque container as direct light is harmful to oils.
