1. Put the breadcrumbs on a baking tray and sprinkle with the sugar, spreading out all of the breadcrumbs evenly and ensuring an even coverage of sugar. Place the tray under a grill on a medium heat, checking constantly to see that the breadcrumbs don’t burn.
2. Keep spreading out the breadcrumbs and returning them to the heat until both the sugar and breadcrumbs have caramelised. Remove from the heat and set aside to cool slightly.
3. Before the breadcrumb-caramel mixture has completely cooled, put it in a bowl, add the milk and double cream and stir vigorously.
4. Pour the mixture into a medium, heavy-based saucepan, stir in the vanilla extract and lemon juice, then place over a medium heat for approximately 10 minutes. Set aside to cool.
5. Pour into your ice-cream maker. Follow the manufacturer’s instructions and leave to churn. (Alternatively, pour the mixture into a freezer-proof container, seal it firmly with a lid and place in the freezer. Whisk after 1 hour to prevent ice crystals from forming; repeat 3 times before leaving it to set).
6. Place in the freezer to let the ice cream set before serving.
