Step 1 In a large, heavy-bottomed saucepan, cook the butter, sugar and honey to a deep, dark caramel color over medium-high heat, stirring frequently. Meanwhile, bring the cream, salt and vanilla to a gentle simmer in a separate saucepan. When the sugar mixture is ready, carefully and slowly whisk in the hot cream (it will bubble, and it could spill over the pan if poured too quickly). Remove from heat and set aside. This makes about 3 cups toffee sauce.
