The scandal of Mrs. Pankhurst and the rhubarb jam resulted in the leader of the suffragette movement setting up a jam factory.
Raspberry jam was very popular in between the 19th and early 20th centuries, but it was expensive to buy, so all kinds of fake versions were made using other foods such as rhubarb (the best) and sweetened turnip (the worst).
Fake ‘wooden pips’ were added to make it look like the real stuff. The trade was so successful that there was, at one point, a profitable trade in making ‘wooden pips’!
Emmeline Pankhurst was shocked however to see the terrible conditions that the women in these wooden pip workshops were under, so she founded her own jam factory during World War One, selling ‘real’ jam.
