When most people hear the word pickling, they automatically think of the standard and traditional pickles. However, food pickling can involve a variety of different foods, not just cucumbers. Historically, people have been pickling eggs, cabbage, carrots and many other food items in order to extend their storage life. Pickling makes this possible due to the high acidity level found in vinegar. Bacteria have a very difficult time surviving in environments with a high acidity level, making pickling an excellent food preservation technique. 

Pickled eggs in vinegar


  • Glass Jar(s)
  • Saucepan
  • Eggs (8-10)
  • White or Apple Cider Vinegar
  • Sugar (1 cup)
  • Salt (2 teaspoons)

*Make sure to disinfect your jars very well before use.

Step 1: Place 8-10 eggs (or however many eggs you would like to pickle!) in a saucepan and fill the pan with water until the eggs are fully covered by about 1- 1 ½ inches.   

Step 2: Cover the pan and turn on the stove to medium heat. Once the water is at a rolling boil, set a timer to 10 min.

Step 3: Once your eggs are cooked, remove from water to cool in a bowl of ice water and peel. 

Step 4: Put a saucepan on the stove and add a cup of white or apple cider vinegar, half a cup of water, a fourth cup of sugar, and two teaspoons of salt. Mix well and bring to a slight simmer. 

Step 5: Gather your jar(s) and fill with your hard boiled eggs. Once all eggs have been placed in the jar(s), cover with vinegar solution. Let your pickled eggs fully season in the fridge for about a week before consuming.
