PUDSEY, UNITED KINGDOM (AFP) – Robert Tomlinson picks rhubarb stalks by candlelight in the dark, carrying on a century-old family tradition that survives today despite the challenges posed to his business by Brexit and climate change.
For four generations, Tomlinson’s family have been cultivating “forced rhubarb” in the winter months at their farm in Pudsey, northern England, and are profiting from a resurgence in the plant’s popularity.
Hundreds of bright pink stems of the “Harbinger” variety reach for the ceiling after they were brought into sheds from fields to be finished off indoors.
The temperature is kept heated to around 14 degrees Celsius, and it is almost completely dark.
With this mildness in the air, “we are tricking them into thinking it is spring”, Tomlinson, 41, said as he walked around his plants, which benefit from a government-protected designation of origin.
In the absence of stronger light, the plants cannot produce chlorophyll and sugar grows in the stalk rather than the leaf, “so you get a far more tender, sweeter stick than you do in summer with outdoor rhubarb”.
The stems can therefore be harvested in winter, when few fresh fruit and vegetables are produced in Britain, and command a higher price than free-range rhubarb, which is typically picked from May.
“You can hear them growing, it makes just like a pop,” said Tomlinson, whose farm lies in a part of Yorkshire known as Britain’s “rhubarb triangle” because of its concentration of growers.
His great-grandfather started growing the plant, which originated in Asia and Russia, in the late 1880s. Until the 1960s, its tangy taste was popular in Britain.
But rhubarb then fell out of fashion and many growers gave up. Today there are only 10 left in Yorkshire, according to Tomlinson, down from a peak of more than 200.
In recent years, however, chefs have embraced rhubarb with relish.
They include Tom Cenci of the 26 Grains group, which manages two high-end restaurants in London which use mostly British produce.
“The recipes are endless,” he said, before sauteing a few pieces of forced rhubarb in orange juice, adding sugar and a little ginger.
Forced rhubarb grown indoors “has a slightly sweeter taste”, and outdoor rhubarb can be more “stringy”. Cenci recommends pairing it with fish or duck.
Forced rhubarb is also used in drinks, from flavoured soda to gin, sparkling wine and syrups.
Tomlinson said the wide array of uses has helped him weather the closure of United Kingdom (UK) restaurants during successive pandemic lockdowns.
Foreign demand has also helped, from restaurants and hotels in Paris, Berlin, Zurich and even New York, he said.
But owing to new customs checks since Britain left the EU’s single market, “it is far more expensive to send it to Europe now”.
And like other British farmers, the rhubarb grower is struggling with labour shortages.
“Costs have gone up. There are so many jobs out there that pay a lot more money,” Tomlinson said.
His wife Paula assists, as do his children aged 13 and 14 on weekends.
Milder weather brought about by climate change is another headwind.
The plants need a period of cold in the autumn “to re-energise before we fetch them in the sheds” for indoor harvesting.
But Tomlinson remains rooted in a longer view of the business dating from his great-grandfather’s time.
“The way in which we are growing is almost identical as it was back then because there is no other way to do it.
“So, I will go on picking by candlelight, by hand,” the farmer said. “There are no machines to do it.”
