LONDON (AP) — Britain's Royal Society of Chemistry says it has perfected the recipe for Oliver Twist's most famous meal — workhouse gruel.

Members of the society consulted historical sources and Charles Dickens' beloved novel to recreate the porridge, which is made from water, oats, milk and an onion.

They plan to ladle out bowls brimming with the gruel, which they describe as "barely palatable," in central London Tuesday.

But the scientists are warning that requests for more — in homage to the famous line, "Please, sir, I want some more" — just won't be tolerated.

The society says it undertook the task of recreating the Dickensian gruel to highlight its work on food.

The tasting comes the week the musical "Oliver!" reopens in London's West End.
