Make each juice and enjoy! Add the lemon juice to the cabbage cucumber juice after you've made the juice.
Whenever possible it is best to use unpeeled vegetables and fruits for juicing for maximum nutritional benefits. Exceptions include beets, which I prefer to peel in order to make sure no grit gets into my juice. I also peel citrus fruit as the skin is bitter.
Chop the fruit and veg roughly before juicing.
You can keep any unused fresh juice in a bottle or jar in the fridge for a couple of days.
