Peer comments suggestion that it would make sense if it were kerosene seems right. There was probably plenty of kerosene around for lamps in nyc in 1905 (although piped natural gas lighting was also common), and kerosene would work fine to turn meat into a burning projectile. Or perhaps to intentionally befoul and ruin the meat for sale, as part of the boycott/protest/riot, with the projectile part being secondary. But yeah, unfortunately the wikipedia source for the burning meat projectile claim is to a web page that makes the same claim without really citing it's source (beyond the name of a historian). We'd have to do some research to see if we could find a cited primary source that this claim came from originally, and how it appeared there. I really like the image regardless. It does not seem implausible to me, generally, with kerosene. But it's an enjoyable image either way.
