Poisonous Escoffier recipe?
Disclaimer: I am not a doctor or a chemist.
The recipe does not tell you to ingest the crushed pits themselves, just the juice that you extracted. The question then is whether you will extract a significant amount of amygdalin using water. This answer on the Chemistry SE suggests using methanol to extract amygdalin from apricot pits. This video also goes into extracting the cyanide from cherry pits, which takes quite a bit more effort than just letting the pits sit in water for an hour.
Thus: the recipe does not neutralize the amygdalin, but the final product is unlikely to contain dangerous doses of the stuff.
