Do you know if this recipe is also in the first edition?

Salmagundi was a composed salad thought to have originated in either France or
Italy in the sixteenth century. A reference to the dish salmigondin is found in
a French text dated 1546. As noted in the OED, Thomas Blount in 1674 reported
that it was an Italian "dish of meat made of cold Turkey and other
ingredients."
