Retaking a thread since 2008 on silk screen printing with cocoa butter, started by @ christina-durta. 10 years later I achieved an advance on the subject.
After having some years in pastry. and then in textile screen printing I was able to get the experience to produce apparently safe edible silkscreen.
If someone is interested in retaking the thread, I can tell you specifically what information I obtained since then. Surely someone can help to understand global regulations for this issue.
Soon more photos and videos!
