Could you advice me on how you imprint in sponge.
I saw a British cake baker show, and the baker made a mixture and piped a design on the baking tray. She froze the tray in the freezer for a few hours and then poured her batter/mixture over the frozen tray.
When she took it out the oven, the cake sponge had the designs in it.
They didn't explain what she used as a mixture for the piping/design on tray.
Any ideas to assist me?
Thank you in advance.
