Chef John's Cloud Eggs

1 . Stage

Preheat the oven to 375 degrees F (190 degrees C). Line a baking sheet with a silicone liner (such as Silpat®) and butter lightly.

2 . Stage

Crack 1 egg into a clean hand and then separate carefully by letting the egg white drip down between your fingers into a large bowl. Reserve the yolk in a separate, smaller bowl. Repeat with second egg.

3 . Stage

Pour vinegar into the egg whites, add salt, and whip with a whisk until we have relatively firm, but not dry, peaks.

4 . Stage

Spoon onto the prepared baking sheet, making sure they are not too wide, as we want some height here. Shape as desired and make a small depression in the top centers using a spoon for yolks.

5 . Stage

Bake in center of the preheated oven until they just start to take on some golden color, 5 to 6 minutes. Add yolks and bake until yolks are heated through, but still runny, 3 to 4 minutes more. Serve on butter toast.
