• 2 medium red onions
• 1 cup white vinegar
• 0.5 cup water

Peel and thinly slice the red onions into rings or half-moons, depending on your preference.

Step 2

Peel and lightly crush the garlic clove with the flat side of a knife.

In a small saucepan, combine the white vinegar, water, granulated sugar, and salt. Heat over medium heat, stirring occasionally, until the sugar and salt are fully dissolved. Do not let the mixture boil.
