I have recently bought a couple of wilton flower nails to put at the bottom of a large cake i was baking to help the middle of the cake cook equally to the rest. When i took the flower nail out the sponge after it had cooled down, the flower nail had gone a kinda black speckly colour, and even a bit of the sponge had black bits on it and when i removed the black bits of sponge, they smelt like metal? I feel like i have baked a cake with a bit old rusty nail in the middle of it? is there any way round this happening? Or have I done anything wrong??
The flower nails are not meant for baking and they discolor. There are companies that make nails for baking.
