- 2 teaspoons sugar
- 1 teaspoon salt
Vegetables
- 1 medium red onion, sliced very thin
- 2 garlic cloves, sliced
Instructions
- Prepare the Onion and Garlic: Thinly slice the medium red onion and garlic cloves to ensure they absorb the pickling liquid quickly. The thin slices will also make the pickled onions optimal for topping dishes.
- Combine Pickling Liquids: In a bowl, whisk together the hot water, white vinegar, sugar, and salt until both sugar and salt have completely dissolved. This hot mixture helps to speed up the pickling process.
- Pack the Jar: Place the sliced onions and garlic into a mason jar or other clean container, packing them tightly but gently to maximize the pickling surface area.
- Pour Pickling Mixture: Pour the vinegar mixture over the onions and garlic, making sure they are fully submerged. This ensures even pickling and prevents spoilage.

Notes
- Using thinly sliced onions accelerates the pickling process and improves texture.
- You can adjust the sugar level based on your sweetness preference; reducing sugar makes it tarter, while adding more softens the acidity.
- Store in the refrigerator to maintain freshness and crispness for up to 4 weeks.
- Adding sliced garlic cloves infuses a subtle garlicky flavor, but you can omit if desired.
