Start by washing the radishes thoroughly under cold water to remove any dirt. Slice the radishes into even rounds, about 1/8 inch thick. Arrange the slices in a large mixing bowl.

Squeeze the juice of half a lemon over the sliced radishes, and add a pinch of salt. Toss gently and let sit for 5 minutes.

Gently massage the radish slices for about 1-2 minutes to release their natural juices.

Drizzle olive oil over the radish mixture, then grate fresh Parmesan and add torn dill leaves. Lightly mix together.

Transfer the salad onto a serving platter, spreading the radish slices out evenly.

Zest the remaining lemon over the top, then sprinkle extra Parmesan, more dill, and black pepper to finish.
