Place over medium heat and bring to almost boiling point. \\nStep 3 Meanwhile, in a bowl, whisk yolks and sugar together until thick and pale. Gradually pour in hot cream mixture, whisking constantly. \\nStep 4 Return mixture to clean saucepan. Cook on low heat 10-12 minutes, stirring constantly until thick enough to just coat the back of a wooden spoon (be careful not to overheat or mixture will curdle). \\nStep 5 Divide custard between ramekins. Pour boiling water into baking dish to come halfway up sides of ramekins. Bake 20-25 minutes until almost set and slightly wobbly in centre. Remove ramekins. \\nStep 6 Cool completely in fridge. Just before serving, sprinkle custards with an even layer of raw sugar. Using a kitchen blowtorch, drag the flame back and forth over the sugar until caramelised."
