This is my basil 'foam' recipe - maybe it will work with lettuce also? You do need to whizz in the last stages to get it foamy! - hope it helps
• 300ml semi-skimmed milk
• handful basil leaves
• 25g butter
• 50ml single cream
place all the ingredients in a saucepan and bring to the boil. Using an electric stick blender, process everything until smooth. Strain and transfer the liquid into a jug and process again with the blender until it becomes foamy.
