Angel Food Cake

From Adam Ragusea

I have leftover egg whites. Should I just throw them away? Try the angel food cake instead!

Ingredients

• 5 egg whites
• 1/2 teaspoon cream of tartar (or a squeeze of lemon juice)
• 175 g granulated sugar
• 1/2 cup (60g) flour (cake flour, ideally)
• salt
• vanilla (or some other extract)

Instructions

• Bake this in a narrow pan — one big loaf pan, or two smaller ones would be good. Line the pan entirely with parchment paper before you start on the batter. Get the oven heating to 350ºF/180ºC.
• Put the cream of tartar in the egg whites and beat to stiff peaks. Gradually beat in the sugar until the foam is stiff again. Beat in a pinch of salt and a splash of vanilla. Beat in the flour until the mixture is just homogenous — no longer.
• Scrape into the pan and bake until a skewer to the center comes out clean — about an hour, but it'll depend on the dimensions of your pan. Let cool thoroughly before taking it out of the pan and peeling off the parchment paper.
• A serrated knife is good for slicing. I like eating it plain, but you could top it with whipped cream, berrie.
