Cloud Eggs (Separated White and Yolk — French Oeufs en Neige Origin)

Cloud eggs went viral on Instagram and Pinterest in 2017, appearing as whipped egg white nests with a golden yolk baked into the centre. While the aesthetic seemed novel, the technique draws directly from the classic French preparation oeufs à la neige — eggs in snow — in which whites are whipped and poached or baked, with the yolk as centrepiece. The viral version simplified this to a home oven format, and the result, when done correctly, is a genuinely interesting textural experience: crisp-edged meringue-like white exterior, soft airy centre, and a warm, barely-set yolk. The method requires separating eggs without any yolk contamination in the whites — even a trace of fat will prevent proper aeration. The whites are whipped to stiff peaks with a pinch of cream of tartar and salt. The peaks must be truly stiff: when the bowl is inverted, the whites should not move. Soft or medium peaks produce a cloud that collapses in the oven. Fold-in additions at this stage are optional but improve the final result: finely grated Parmesan, crumbled prosciutto, finely minced chives, or herbs. These should be folded very gently with a silicone spatula to avoid deflating the whites. The nests are spooned onto a parchment-lined baking sheet in mounds with a well pressed into the centre using the back of a spoon. The nests bake at 450°F for 3 minutes to set the exterior, then the yolks are carefully lowered into the wells and the eggs return to the oven for another 3 minutes — this gives a set white with a runny yolk. An additional minute produces a medium-set yolk. The critical error most home cooks make is baking too long: the whites toughen and the yolk overcooks from the ambient heat.
