When I was a kid my grandmother used to fix frog legs this way and I still fix them like this now. Nothing fancy, just simple old fashion cooking.
- Soak frog legs in milk for 1 hour, turning every 15 minutes.
- Remove from milk and salt and pepper them lightly, and coat them in flour.
- In a skillet bring the butter to a sizzle and add frog legs.
- Sauté legs uncovered until they're golden brown on both sides (turning as needed).
