Fire up a large skillet. Medium-high.
Spray evenly with cooking spray.
Add the radishes. Using a wooden spoon, tumble the radishes in the pan while blistering and browning, about 1 minute. There are plenty of natural sugars to play with in those radishes.
When the radishes look toasted in areas and slightly pan-charred in others, lower the heat somewhere between medium-low to low (essentially, we want the radishes to sweat now, not roast, so low and controlled is the answer).
Tumble again. Monitor while the radishes collapse a bit. You'll see them getting tender before your eyes. Cook for about 6 minutes, tumbling occasionally.
Pierce one with a fork, not a knife. If it's tender, pick it up ceremoniously. Wave it in the air to cool it down. Sway your hips, too. It's cool to dance when you cook. Now, taste. You'll want to experience this flavor, even pre-seasoned.
Hopefully, they're not quite ready yet. Add the butter, the thyme sprigs, and the smashed garlic clove to the pan. Raise the heat to medium-high. Tumble for about 1 minute, allowing the garlic to toast. Season with salt.
Now here's a meal: Serve hot alongside the Cocoa-Crusted New York Strip and Maria's Cilantro Cebollas.
