What happened when the angel of the LORD touched Gideon's meat and bread with his staff?

Answer: Fire from the rock consumed it

Fire flared from the rock and consumed the meat and the unleavened bread, and the angel of the LORD vanished from Gideon's sight.

“Then the angel of the LORD extended the tip of the staff that was in his hand and touched the meat and the unleavened bread. And fire flared from the rock and consumed the meat and the unleavened bread. Then the angel of the LORD vanished from his sight.”— Judges 6:21 (BSB)
