  • Chef knife
  • Cutting board
  • Measuring cups & spoons
  • Medium saucepan
  • Mason jar


  • 1 large red onion ($0.69)
  • 2 cloves garlic ($0.04)
  • 1 cup white vinegar ($0.16)
  • 1 cup water ($0.01)
  • 2 teaspoon salt ($0.02)
  • 1 ½ tablespoon cane sugar ($0.01)
  • 1 teaspoon whole peppercorns ($0.01)

Additional seasonings optional

  • 1-2 teaspoon Mexican oregano
  • 1 bay leaf
  • 1-2 whole cloves
  • A few Jalapeño slices
  • A pinch of whole cumin seeds
  • A pinch of whole coriander seeds


  • First, peel your onion. Then, cut it in half and thinly slice the whole thing. Peel and crush the garlic (this will help release the flavor). Set aside.
  • In a medium saucepan, bring the water, vinegar, salt, and sugar to a light boil. Mix in the onion slices, garlic cloves, and whole peppercorns.
  • Turn off the heat and let the saucepan sit covered for 10 minutes. Then, add the onions to a mason jar and pour the liquid over top. Lightly tap the jar down on your counter to get rid of any air bubbles.
  • Let the jar sit for another 20 minutes, then serve immediately or put the lid on and transfer to your fridge for storage.



  • Use any combination of white vinegar, apple cider vinegar, white wine vinegar, or rice vinegar.
