1 bunch radishes
good quality bread, such as an artisan baguette
chopped fresh parsley or microgreens for garnish (optional)
An hour before serving, clean and trim the radishes and transfer to a bowl of very cold water. Let them sit for an hour; this crisps them up again if they've gotten slightly soft.
Slice and butter your bread. Thinly slice the radishes and cover the bread with radishes, overlapping slightly. Sprinkle with salt and garnish, if desired.
