What are the sultanas mentioned in the recipe for My Grandmother's Ginger Jam Bread And Butter Pudding?
Nigella's recipe for My Grandmother's Ginger Jam Bread And Butter Pudding (from NIGELLA BITES) is made with brown bread and ginger jam and includes sultanas that have been plumped up with rum.
The sultanas in the recipe are a dried fruit made from a white grape that has a yellow skin. When dried, the sutanas retain a lighter (in comparison with raisins) or golden colour and in some places they are called golden raisins or golden sultanas. If you can't find sultanas/golden raisins then you can use the same quantity of regular raisins instead. There is also a fresh grape called a sultana, but this fresh fruit is not suitable for the recipe.
