You have to admire egg whites. I mean there they are, looking like snot run amok, until you beat them mercilessly and they attain their full glossy glory. If you add sugar, cocoa powder, and yes, a teaspoon of red wine vinegar, you've got Nigella Lawson's recipe for "Gooey Chocolate Stack" well under way, my friend. The egg whites will transform into three lovely meringues (or orangutans, as Will called them).
As for the six yolks that have been divorced from their whites, you beat those (with less dramatic results) with cream, sugar, and milk, and add melted bittersweet chocolate and vanilla and you've begun creating the chocolate creme de patissiere to dollop over the big flat meringues. Like Nigella says, chocolate heaven. I brought this to a New Year's brunch and it was devoured. Even though Jack and Will say they like Hershey's chocolate better than the Scharffenberger's I used, they had no objections to eating this rather adult confection. I found a copy of the recipe here, with no attribution. It's from How To Be A Domestic Goddess, p. 185. I couldn't find pistachios so I sprinkled slivers of honey roasted almonds over the top. If I ever find candied violets, I'd like to use those. I am in love with just the idea of candied violets.
Oh, if you make this? Please be advised that Nigella may be a relaxed cook but when she says to make the meringues eight inches across, she means eight inches. So don't make them nine. Because then the meringues will be too thin and the chocolate creme will absorb them. And also? Please do assemble this layered creation just a few minutes before eating, because, again, the absorption situation. The meringues must be crisply separate and distinct from the creme for maximal mouth feel. (Why am I talking like this?)
We don't eat meringues so much in the U.S. and I don't know why. They are often called pavlovas in Britain and Australia and have a fruit sauce. Nigella's word for the meringues in this recipe is "gungy," British slang for, well, pretty much exactly what the inside of a meringue is like. On this side of the pond we have no slingue to describe meringue. Our loss.
