Earlier, we noted that La Esquina served grasshoppers at the bar during the Spotted Pig’s Super Bowl party, and there’s more reason to believe entomophagy is catching on. Next Tuesday, the Gastronauts, last seen eating python, will hold a bug-eating dinner at a “posh apartment.” Their master of ceremonies will be David Gracer, a Rhode Island enthusiast who lectures on edible insects and serves them at private parties. Gracer recently wrote on his blog, Bugs for Dinner!, that he was bummed he couldn’t find markets selling them in New York. To help Gracer in his quest, we turned to Miguel Calvo, a mixologist who will be serving cocktails rimmed with grasshopper salt at Crema this Valentine’s Day.
