My husband’s grandmother, Frances Leahey, brought home this recipephany from a cooking class sponsored by the Western Massachusetts Electric Company and its live-wire mascot Reddy Kilowatt in the 1940s. She had just bought an electric oven, and the class was, according to Reddy, to help “our electric customers to make the very best possible use of the electricity they buy.” There is no better use of electricity than this pie.
At first, Ma thought this recipe was the case of a lemon meringue pie gone awry, where the teacher mistakenly folded the egg whites in with the filling instead of spreading them on top. Whatever its origin, lemon sponge pie took the family by storm, and is now in its fourth generation of sweetening holidays, family reunions, celebrations and all-around good times.
The pie performs that magic trick of separating into golden cake on top and tart lemon filling below. It holds together so well, the tradition is to eat it as a finger food. You pick up a wedge right out of the pie pan, holding a napkin below simply to be polite. I prefer a fork and plate, though, to slow me down and help delay my rush for seconds.
The recipe below has evolved from Ma’s original. My mother-in-law Dorothy, the best baker ever, added more egg, flour and butter. My sister-in-law Chris, who recounted the pie’s history for me, upped the juice to 5 tablespoons many years ago. Now she advises that a half cup is even better, and she omits the lemon rind. So if you have a real lemon urge, feel free to adjust the tartness to your palate. Chris also went from 3 to 4 eggs, for more fluff on top and more creaminess inside. I find that 2 large and 1 jumbo will also do the trick. Apparently with this pie, more is better. Especially on the table.
