This is an easy dark fruit cake or tea brack, which involves soaking dried fruit in strong black tea overnight. Barmbrack was traditionally served at Halloween in Ireland. Items, such as a ring to signify a wedding in the near future, would be wrapped up in paper and baked in the cake for one lucky person to find in their slice! There's no butter required for the recipe itself, but it's worth buttering every slice of this. Stored in an airtight tin, this cake will keep for 10 days.
