1. In a saucepan, the bring More Than Gourmet White Wine Sauce to a simmer and cook 2-3  minutes to reduce the sauce slightly.
2. In a mixing bowl, whisk together the egg yolk and the cream.
3. Remove the More Than Gourmet White Wine Sauce from the heat and whisk a small amount of it into the egg/cream mixture. Repeat until you've added about a third of the sauce. Slowly pour this mixture back into the pan, whisking constantly.
