Can the Yellow Split Pea Soup (soup minus the frankfurters) be frozen?
Most soups freeze well and Nigella's Yellow Split Pea And Frankfurter Soup (from Feast and on the Nigella website) can be frozen. It is easier to freeze the soup without the frankfurters, but if you are freezing leftovers than it can also be frozen with the frankfurters in.
Cool and chill the soup in a non-metallic bowl then transfer it to a large airtight container (or freeze individual portions in smaller containers). Seal tightly and freeze for up to 3 months. Thaw the soup overnight in the refrigerator. To reheat the soup transfer it to a saucepan and heat gently, stirring frequently, until the soup is piping hot. Add the frankfurters, following the instructions in the recipe. If the frankfurters were frozen in the soup then check that they are also piping hot all of the way through before serving the soup.
