Slice the skin from the lemon. Roughly chop the spinach. Chop the turmeric into small chunks. Quarter the apples and slice out the core.Pop them all in your blender with the cashews (see our tip about soaking them) and pour in the coconut water. Add a cupful of ice. Blend till smooth.
Soaking your cashews in water overnight helps to remove enzymes that inhibit the body from absorbing the nutrients. Cover them with cold water and a pinch of salt and soak for at least 6 hours. Drain, then follow the recipe.
