Serves: 1 litre of ice cream1) Heat the single cream until it forms bubbles around the edge of the pan and steam starts to rise. Meanwhile, in the bowl of an electric mixer fitted with the paddle attachment, beat the egg yolks, sugar, and salt until mixed. Slowly add the hot cream until combined. Wipe out the pan and pour the mixture back into the clean pan. Cook over medium-low heat, stirring constantly with a wooden spoon, for 5 to 10 minutes, until it's thickened and the cream coats the back of the spoon.
