Step 1Trim the tops from the radishes and wash and pat dry. Chop some of the brightest and freshest tops to make two-thirds cup.
Step 2Pulse the chopped tops with the goat cheese in a small food processor until nearly smooth.
Step 3Thinly slice the radishes. Slice the baguette thin and lightly toast.
Step 4Spread 2 to 3 teaspoons of the goat cheese mixture on each slice. Top each slice with 3 or 4 radish slices and sprinkle with coarse salt. Serve on a platter lined with remaining radish tops.
