My arse it’s grown by candlelight.
Forced rhubarb is grown by only 12 producers in West Yorkshire in damp, dark sheds, and harvested by candlelight in mid-winter. Forced rhubarb has a more delicate flavour, tender stalks, and red colour than varieties of rhubarb that are grown outdoors. It is considered to be superior to rhubarb harvested outdoors.
