Here’s how to leach out the toxic tannins from the acorns. Tannic acid, which causes nausea and intestinal upset when eaten, is washed away by this method.

  • Choose brown acorns that are fully ripe and still have their caps intact. Green, unripe acorns should be avoided since they contain more tannins.
  • Remove any impurities, such as dirt and small insects, by thoroughly rinsing your acorns. Any rotting nuts should be discarded.
  • Crack open the acorn nuts.
  • Separate the shell fragments from the nut flesh bits.
  • Immerse the flesh in a basin of hot water. 
  • Soak them for a few hours in warm water, then drain the water. 
  • Carry out a taste test on a very small piece of an acorn. If the acorns are still bitter, soak them for a few more hours.
  • Repeat soaking till they’re to your taste to your liking.

You can also boil the acorns in water rather than soaking them. However, boiling does not remove all the bitterness from the tannings.
