Wong Kit-wing, dim sum chef of the Golden Leaf restaurant at the Conrad Hong Kong hotel, shows us how to make traditional white lotus paste mooncakes with salted egg yolks. Not an oxymoron: six healthy Hong Kong mooncakes for Mid-Autumn Festival First he prepares a syrup. He melts coarse and fine sugar in boiling water and adds pineapples, lemons and preserved plums for flavour, then simmers it for three hours. Next, he mixes flour with the syrup to make the dough, which is left to rest for an hour. To make the individual mooncake crusts, he breaks the dough into pieces, flattens each one with his hand and uses the flat side of his cleaver to make the skin even thinner. Chinese city’s record 2.4-metre-wide Mid-Autumn Festival mooncake cut down to size for hungry fans Next he puts the salted egg yolk into the lotus seed paste, into the crust and shapes it into a ball. The ball is put into the wooden mould and he knocks it against the table to get the mooncake out. Why Are There So Many Different Kinds of Mooncakes? The mooncakes are baked at 300 degrees Celsius for about 12 minutes. Halfway through the bake he takes them out and brushes the tops with egg wash. The mooncakes cannot be eaten right away. They must sit for about seven days for the baked crust to absorb the oils from the salted egg yolk and lotus seed paste for a better taste.
