Pulse all ingredients except juice in a food processor until you have a coarse meal.
Add the orange juice and pulse until mixture sticks together.
Roll about 1 teaspoon of the mixture into a ball and roll in one of the optional ingredients. Repeat with all of the mixture. Place in the fridge for a while before serving to allow them to firm up.
Serving Suggestion: excellent served at the end of a meal as an alternative to the "after-dinner mint", or with tea at an afternoon tea.
