Melt the butter in the pan over medium heat. Add the radishes with a pinch of salt. Cook over medium-high heat about 3 minutes. Shake the pan to turn them to brown on all sides.
Reduce the heat to medium-low. Add the lid and cook, shaking occasionally, until fork tender and brown, about 5 to 8 minutes.
Add the lemon juice, chives, tarragon, and the rest of the salt. Toss. Taste for seasoning, and serve over a bed of the cooked radish greens.
