SAEDNEWS: Pickled Onions: Traditional Iranian Crispy Red Onion Pickle Recipe (Step-by-Step)
According to Saednews, This pickled onion is one of the most popular restaurant-style pickles, usually served alongside traditional Iranian dishes. Follow the step-by-step instructions below to prepare quick pickled onions.
Red onions: 1 kg
Purple cabbage or beetroot: 1/2 piece
Garlic: 5 cloves
Green chili peppers: 3
Apple cider vinegar or red vinegar: 3–4 cups
Sugar: 2 tablespoons
Salt: 3 tablespoons

First, peel and wash the onions. Then slice them into thin strips. The thickness depends on your personal taste. You can also use whole onions if you prefer. If slicing, cut the onions in half first and then slice them evenly with a knife. Spread the sliced onions on a cloth and let them dry completely.
Next, wash and chop the purple cabbage, or alternatively peel and grate the beetroot (coarsely or finely). Either option works, as they are mainly used for color rather than flavor. Peel the garlic cloves and chop them finely. Place all ingredients on a cloth to remove excess moisture.
Take a clean and sterilized glass jar. Layer the ingredients inside it: first some onion, then chili, garlic, and cabbage or beetroot. Repeat these layers until the jar is full. Press down firmly with your hand to eliminate air gaps and pack everything tightly.
In a separate container, mix vinegar, sugar, and salt well. Pour the mixture into the jar until it is completely full. Seal the jar tightly and keep it at room temperature. After 48 hours, the delicious pickle is ready to serve alongside your meals and side dishes. Enjoy!
You can use apple cider vinegar.
Adjust the amount of hot pepper according to your taste.
All ingredients must be completely dry to prevent mold.
