I’ve been doing this with some of my colours. You can buy now all natural food colouring. But it is very expensive. Although I believe that you need much less of the natural colours. I’m also no longer using plastic straws for dowels in my cakes. I’m using wooden dowels because they are compostible. I only use my own homemade cake boards, also compostible.
