Wash and chop the vegetables
Put all the ingredients in a big pan and stir to mix well
Cook on low for circa 45-50 minutes, stirring occasionally, with the lid on the pan but slightly off, to allow some steam to escape
Turn off the hob, remove the bay leaves and let the remaining mixture cool for a few minutes before adding it to a trusty blender and blending, until smooth
I then dish mine out into an ice cube tray, 1 tbsp per ice pod
They last circa 8 months in the freezer
