When’s the last time you made ladyfingers? What? You can’t remember? And what the heck are they, anyway? Well, they’re sort of finger-shaped sponge cakes made from an airy batter of beaten egg yolks and egg whites and cake flour. I learned how to make them watching Julia Child on the French Chef episode “Introducing Charlotte Malakoff.” I get a thrill whipping up whites and yolks, and Julia made everything look so easy, I decided to try my hand at them. You can watch this episode on Amazon.com. Julia Child, The French Chef, Season 3, Episode 10.
