Notes
Types of cucumber
For this recipe, you want to choose a seedless or almost seedless variety with a thin skin. We use English cucumbers as they are most commonly available to us. Other smaller varieties such as Persian cucumbers and Japanese cucumbers are a good option and will produce a less watery pickle.Half an English cucumber weighs around 150-200g and is roughly equivalent to 1 Persian cucumber or 1 ¼ cups sliced.
