It might be the coldest season, with the shortest days and darkest nights, but that doesn’t mean you only have to eat hot puddings and heavy crumbles made with spices and dried fruits. Why not bake your way to sunnier climes with recipes that let citrus fruits shine? Try favourites such as lemon meringue pie and key lime tart, as well as fruity twists on classics like lime panna cotta and lemon Swiss roll.
