The list of ingredients for sabayon is short and it seems that everything is simple, but the devil, as always, is in the details. Mistakes in the choice of cooking utensils can turn the luxurious dessert into an omelette before you realize you've made a mistake. Cook your dessert in a copper bowl - the copper distributes the heat evenly and lets you control the cooking process. If there is no copper, take a glass bowl, glass has good insulating properties, the cooking process will take longer, but it will also not get out of hand. And we will leave the stainless steel for the pros.
