With a fork, whisk together eggs, heavy cream, salt and pepper.
Avoid creating a froth when whisking the eggs, to avoid a crust around the edge of the pan
Heat the butter in a pan on medium heat, then carefully pour egg mixture into pan.
Allow the eggs to cook a little until you have a layer of egg at the bottom of the pan, then begin gently scrambling.
Continue scrambling until the eggs have a light sheen to them, then remove from heat.
The eggs will continue to cook just a little.
Spoon equal amounts of creme fraiche into bowls.
Do the same with the scrambled eggs on top of the creme fraiche.
Place a small amount of caviar on top of the eggs in each bowl until you've used up the entire 1 oz
Serve immediately with champagne or sparkling wine
