Sticky toffee pudding is a British classic. It was always had a place on dessert menus when I was working in restaurant kitchens, whether it was the middle of a cold winter or a record breaking summer.
I've come across a few variations on recipes that, inevitably, revolve around the key ingredient... dates. Some use black treacle, some, like mine, soak the dates in black tea, some use a selection of spices, and others keep it to the basics.
Which ever way the recipe goes, you'll rarely find a sticky toffee pudding without butterscotch sauce.
