My Mom would buy it and feed it to the family and none of complained at all.As I recall it tasted great and was more tender than most of the beef that was available via the ration book.
Same thing in the 1970’s when Nixon (idiot) enacted wage and price controls. Along with Carter’s later stagflation, horsemeat was sold a lot in NY and NJ and other big cities.
I remember an “All in the Family” epsiode about eating horsemeat.
