Equipment

  • sharp knife or mandolin
  • 1 clean glass jar with lid or mason jar.

Ingredients
  

no-cook pickles

  • 2 red onions
  • 100 ml raw apple cider vinegar
  • 100 ml water
  • 1 tablespoon maple syrup
  • 1 teaspoon sea salt or himalayan salt.

flavourings

  • 1 teaspoon fennel seeds
  • 1 teaspoon mixed peppercorns

Instructions
 

  • Slice the red onions thin. Peel the outer layer from the onions and discard. Half the onions to make them easier to slice. Using a sharp knife or mandolin finely slice the onions then push them into the jar until it's filled to the top.
    2 red onions
  • Add the flavourings: Add the maple syrup, salt and flavourings to the jar and push everything down using a fork.
    1 tablespoon maple syrup, 1 teaspoon sea salt or himalayan salt., 1 teaspoon fennel seeds, 1 teaspoon mixed peppercorns
  • Pour over the pickling liquid: Pour the raw apple cider vinegar into the jar until it comes up halfway. Top the jar up with water leaving a small gap at the top. Screw the lid on nice and tight then shake the up jar gently to mix all the ingredients together.
    100 ml raw apple cider vinegar, 100 ml water

Notes

Storing: Store in a lidded jar in the fridge to keep fresh for 2-3 weeks. Be sure the onions are completely submerged in the pickling mixture so that they stay fresh. 
If you have time, allow them to sit at room temperature for 30 minutes so the flavours can start to develop, before placing them in the fridge. (optional)
