while grasshopper pie is most commonly known these days as a type of ice cream pie, it started off as a mint and chocolate chiffon pie based on a prohibition-era cocktail. a chiffon pie filling involves stabilizing flavored and sweetened whipped egg whites or whipped cream with gelatin. the results are light, airy, and delicate. we wanted to go retro and bring back the original chiffon version of this pie and here''s what we discovered
test kitchen discoveries
for a mint-flavored crust, prepare it with minty oreo cookies (mint u2019n creme). the cookies can be ground to uniform crumbs in seconds in a food processor or sealed in a zipper-lock bag and smashed with a rolling pin.
use two liqueurs to flavor the filling: creme de menthe and white creme de cacao. we found no substitute that contributed a similarly intense flavor.
make sure to fully hydrate the gelatin or tough bits may punctuate the otherwise silky smooth texture of the filling. once dissolved in the cream, the gelatin should be heated until it''s very hot, but below a boil.
beat the cream to smooth-looking stiff peaks. a chunky or grainy texture is indicative of the cream being overbeaten. for the most stable whipped cream, start beating the cream slowly, and then increase the mixer''s speed once the cream is beginning to build in volume.
make sure the pie is fully set before serving; otherwise the filling may ooze once sliced. six hours should be sufficient; overnight is better.
