For the violet sugar:
Place half of the sugar into a mortar and pestle bowl. Spread the violets over the sugar. Top with the remaining sugar and lightly crush the sugar into the violets. Cover the bowl with a clean, thin, dry dish towel until the flowers are completely dried out, which could be a couple of days depending on the humidity in your area. Sift through an open strainer.
For Devine Overnight Oats:
Wash fruit and set aside.
Mix the rest of the ingredients (including violet sugar) in a bowl and store in fridge over night.
In the morning stir oat mixture. Add more milk if need be.
