Peel the ginger with the edge of a spoon to remove the ginger's outer skin.
Slice thinly with a mandoline or sharp knife.
Place the ginger slices in a bowl and sprinkle with 1 teaspoon salt. Mix with your hands to coat evenly. Leave for 10 minutes.
Bring 2 cups water to a boil in a medium saucepan. Add the ginger slices and simmer for 15 minutes.
While the ginger cooks, combine rice vinegar, sugar, and ½ teaspoon salt in a separate saucepan. Warm over medium heat until the sugar dissolves. Do not boil.
Wash, peel, and slice the beetroot into 1 cm discs. Add to the vinegar mixture and stir for about 2 minutes to release a pink color. Remove from heat.
Drain the ginger and allow it to cool completely. Squeeze out excess water with clean hands.
Transfer the ginger to a clean, sterilised glass jar. Pour over the pink pickling liquid until the slices are fully submerged.
Seal and refrigerate for at least 3–4 hours before serving. Best flavor develops overnight.
