Banoffee Pie
The toffee layer is the only stage that takes time: an unopened tin of sweetened condensed milk simmered in water for 3 hours turns into deep amber dulce de leche. The biscuit base is digestives crushed and bound with melted butter, pressed into a tart tin and chilled. The toffee goes on cold, the bananas are sliced just before serving (so they don't brown), the cream is whipped to soft peaks. Assembled in order. Dusted with cocoa or grated dark chocolate. Cut with a knife dipped in hot water for clean slices.
