What's your current method?
I bang my molds on the table a few times, it's not perfect, chocolate shards fly everywhere, and maybe that's why there are so many little scratches on my marble 😆
Then I line them all up on edge in the sink and spray the rest off with hot water. I do have a grease trap but still try to minimize the fat that goes down the sink, because guess whose job it is to clean it out later? 🤢
