This is a view from the competition part of the festival. This baker had already formed, sliced and chilled those little scrolls in two colours. Now he alternates them in the baking tray. For the small one, he started by zeroing his electronic scale with an empty tin on it. He filled the tin, and weighed it again on the very accurate scale. Yep, exactly 100g. That's the sort of precision needed in competition! I notice he's using silicone bakeware - now I'm sure it's not cheating.
