A few months back my newsletter was about ten non-salad ideas for radishes. One of them was roasting, so I'm backtracking a little to throw this idea out there again.
This technique yields a particularly tasty radish.
It's so simple there's really no recipe.
Just put a sheet pan in a 450 degree oven for 10 minutes. Schmear on a little oil and spread out some sliced radishes (of any variety) and roast for about 15-20 minutes. You can even leave the greens attached for a little extra punch.
And no brown = no delicious.
