Allspice (Pimenta dioica) is a popular spice in many British Christmas recipes and aromatic decorations. You would be forgiven for thinking allspice was a mixture of spices, but it’s actually the unripe berry of an evergreen tropical shrub. The name allspice was given to it by English explorers because its flavour resembles mixed spice. Try our allspice Christmas decoration tutorial to fill your home with the delicious scent of allspice.
