You can use chicken stock instead of the vegetable stock.
This recipe takes its inspiration from Jean-Claude Brisville's play "Le Souper " (The Supper), which shows a supper – possibly imagined – shared by Fouché (Napoleon's chief of police) and Talleyrand (Napoleon's crafty chief diplomat) on the eve of the restoration of the Bourbon monarchy in 1815.
Talleyrand is hosting in sumptuous style, his personal cook Antonin Carème is in the kitchen, and among the dishes on the menu is "Asperges en petits pois", for which he gives Fouché the recipe, saying it comes from a certain Monsieur de Cussy (Chief Steward of the imperial household under Napoleon, then under Louis XVIII).
It's a terrific historical drama (you can watch an extract here
and test your French!), which was later made into an excellent film.
