It's a Garum spreader.

"The very best garum, according to the Geoponica, is called haimatum.
It was made with solely the innards of the tuna, including blood and
gills. These are put in a pot with salt, and after two months the
liquid is garum."

Dead fish, hot climate, sounds yummy.

Every society close to an ocean has had its version of "fish sauce";
almost always a salty concoction, since salt was one of the few effective
preservatives.

There was a time when food was difficult-enough to obtain (or afford)
that no scrap went wasted. (using "everything but the squeal" was an old
pork butcher's phrase)
