Heinz, the nation’s kings of ketchup and bosses of beans, has launched an all-new condiment – Fish and Chips sauce.

The company describes it as a sort of supercharged version – a “hot new upgrade” – of traditional tartare sauce.

It hopes that the “fresh and herby” product will become “Britain’s new go-to pairing for fish dinners.”

In its research, Heinz said fish is becoming more popular for British diners each year.
