ways to peel roasted peanuts

How to Peel Roasted Peanuts

Quickly peel the roasted peanut by rubbing them between your palms. To separate the peel, use a blow dryer. I recommend using the Blowdryer Technique on a clean and open surface for easy clean-up or No-Mess Air Fryer Technique.

Peanut Oil Variations

Redskin peanuts are recommended, but you can also try other varieties. If you want to add more flavor to the oil, incorporate salt, honey, cocoa powder, sugar, and more!

If you don’t have a blender or food processor, you can also use an immersion blender, a food mill, or other similar kitchen tools. Alternatively, pound the peanuts using a mortar and pestle until you achieve consistency. 

  • Blender or food processor: Make the oil in a food processor. 
  • Oven: Roast them in the oven for easy peeling and a stronger flavor.
  • Spatula: Scrape the sides of the food processor with a spatula. 
  • Airtight jar: Store the contents in an airtight jar. 
  • Baking tray: Spread the peanuts on a baking tray.
