Chips de Radis Noir

2 large black radishes
olive oil
balsamic vinegar
salt, pepper
red pepper flakes
Serves 4.
Preheat the oven to 220°C (430°F). Grease a baking dish (unless it is non-stick).
Wash and scrub the radishes. Peel them with a vegetable peeler, leaving half of the peel in stripes if desired. Slice the radishes thinly - very thin slices will be more chip-like, slightly thicker slices will be moister - and put the slices in the baking dish.
Pour a little olive oil, a little vinegar, sprinkle salt, pepper and red pepper flakes. Toss with a wooden spoon to coat. Pour and sprinkle more if necessary, until all the slices look comfortably dressed - but not drenched.
