Trim both ends of the radishes, wash well to remove any grit. Dry with paper towels then cut in half lengthwise, then slice each piece into half moons, thickness is up to you. not to thick and not to thin. Add the sliced radishes to a mixing bowl. Slice the spring onions, add the white parts and some of the green to the mixing bowl, reserve some of the green parts for garnish.

Add sour cream, say a spoonful at a time and mix into the radishes, goal is a creamy texture without the radishes dripping in sour cream. Taste and season with salt as desired.

Sprinkle the salad with the remaining green part of the spring onion and serve immediately before the water from the radishes leach out. Enjoy.
