Sliced radish and butter, finished with a pinch of salt is a simple French snack where the butter cuts the hot pepperiness of the radish, giving you an indulgent low-carb treat in seconds. I use butter very rarely, otherwise, but it does work here. This is my homemade version of the popular French snack. Use the best radishes you can find (the greens should be bright and not wilted, and the radish should be firm) and quality butter at room temperature.
Cut each radish in half and arrange them flat side-up. Spread a little butter on each half and finish with a pinch of salt.
Alternatively, you can serve the trimmed radishes whole with only a little bit of the top cut off. Serve a side of room temperature butter and flakey salt in two small dishes for dipping.
