I'm making a mermaid cake for DD's birthday. I'm making 2 identical Madeira sponges. The first one, is ready to go in the oven but I've stupidly messed up the 2nd one. I whisked the flour in instead of folding it in. I've just realised and starting folding it in and I've added milk and got it to a nice consistency. Do I need to start the second sponge again? Please help!
