Im quiet new to cakecentral hope this reach for help isn't inappropriate just I have been searching everywhere for the help with no luck. I have been making cakes for couple months and been fine was asked to do a wedding cake today which im always a bit reluctant to do just because it's someone's big day and not sure im at the intracut level yet, but this customer wants a 2 tier wedding cake 1st tier completely plain white icing which is fine and second tier the same with a red rose in middle thats all fine but its to feed 200 people. Had a little look into it and guessing i need a 16" square cake and 14" square cake. This is where my problem starts as all the recipe's for madeira i have only go up to 12" and im not too sure how to multiply recipe's so wondered if anyone had a recipe i could pich or point me in the right direction.
Thank you Glenn
