Mistakenly swallowing something while fasting
Q:
1. During Ramadhaan, I was baking a cake and whilst mixing, the chocolate powder went everywhere and I could taste it in my throat. The chocolate powder must have gone down my throat because it got stuck at the back of my throat. When I swallowed, it went down. Did this break my fast, and is kaffarah necessary?
2. Does swallowing (loose) skin on the lips break the fast?
