They were getting help from a Swede and his daughter. The daughter pulls out a can of Surstremming, and the British half of MM had to leave the table when he got a whiff of the contents.
He didn't appreciate the what a delicacy it is.
Of course, the Romans thought dormice were a delicacy. Even raised them for consumption.
Surstremming would made great bait for crabs and lobbies.
The Romans also had their own rotten fish sauce -garum.
Dumped it on everything. It was like Roman ketchup.
