A "four-egg-yolks" mooncake, which contains four whole salted duck egg yolks with gummy lotus seed in one cake selling at HK$40 ($5), is displayed at a bakery in Hong Kong September 15, 2004. Mainland Chinese customers are turning to Hong Kong for their annual fix after a series of food scares back home, with Hong Kong bakeries scrambling to hire staff to churn out hundreds of millions of the round, palm-sized cakes - each of which has more calories than a McDonald's Big Mac - as their delivery hotlines ring off-the-hook.
