Mulberry trees are traditionally grown for their leaves — mainly in Asia and North America — as they’re the only food that silkworms eat. They carry colourful berries — most commonly black, white, or red — that are often made into wine, fruit juice, tea, jam, or canned foods, but can also be dried and eaten as a snack.
Mulberries are hard to come by in shops, but the UK has a bountiful supply of mulberries to forage from. Black mulberries are generally considered far tastier than white mulberries, having a sweeter taste compared to the white’s more acidic tang. Fortunately, the majority of mulberries found in London are of the black variety, which ripens in late July and August.
