Sterilize the jars. To do this, wash the jars and lids thoroughly with hot soapy water and rinse very well. After this, carefully pour boiling water into the jars and lids. After this, using a folded tea towel (to protect your hands), carefully empty the hot water from the jar. Allow to air dry. (see note 1). Peel the radish. Then thinly slice the radish as desired. (see note 2).
Pack the cut radish into the sterilized jar.
In a small saucepan combine the sugar, salt, vinegar, water, and turmeric powder. Place over medium to high heat, stirring until the sugar dissolves. Bring to a boil.
Taste for seasoning and add more salt and sugar if desired.
Pour the hot pickling liquid over the radish in the jar, making sure they are fully submerged in the liquid. Then seal the jar. (see note 3).
Cool at room temperature for at least 30 minutes and then place in the fridge overnight to allow the flavors to develop.
