So James said to me the other day 'hey Alice, can I please buy 5kg of Nutella'... I obviously said no, but I accepted the challenge instead.
The recipe I used was

I didn't use dark chocolate because I had some leftover from a student that was just an ordinary Cadbury milk. So I used that instead. Tastes amazing! Feels natural and also makes me full. Normal Nutella is so moreish that you can just eat and eat and eat. The hazelnuts are so filling that I don't need nearly as much!
To make it zero waste, the chocolate, hazelnuts and salt are all bulk bought. I haven't been able to find zero waste vanilla essence, but I tend to buy the biggest amount that I can.
