Heat water, vinegar and sugar together until it comes to a boil in a saucepan.
1 cup water, 1 cup vinegar, 3 tbsp sugar
Apply salt to the vegetables and add them to the sterilized jars. Alternatively, you may add salt to the vinegar solution too.
1 tbsp salt
Pour the solution into the jar, leaving some space on top. Tap it once the vegetables are immersed in the solution to gently remove air bubbles.
Cap the jars and invert once or twice so that the salt and solution mix well. The mixture is hot, so handle the jar carefully.You can serve it after 30 minutes, by then it cools to room temperature.
