Welcome to the Cake Decorators Q&A
Hi going to be covering 5 tier wedding cake 14,12,10,8 and 6 inch I have bought Massa tasini. 7 kgs tub I am unsure if that is enough would I be better buying extra
According to the product information on the Cake Decorating company site, 1K OF Massa covers a 10" cake. It doesn't say whether that is a round or square but I should think that will be for round. The pail contains 7K. To calculate how much coverage that will give rolling to 3mm, can be worked out by selecting the sugarpaste calculator on our site here:
Please let me know if this helps or if you would like more information.
