At Beijing Banquet, the ingredients get the royal treatment from a kitchen that celebrates freshness and tradition, Mike Peters discovers.

The ripe, purple-red waxberries are bursting with sweetness in their chilled bowls－so enticing that I fear I will get too full to eat anything else.

In the end, there was little danger of that. The onslaught of dishes that followed at Beijing Banquet, served traditionally on a lazy Susan-style tabletop that never seemed to stop turning, was just too tempting.

First came a distinctive smoked pork that was cooked so slowly it's almost gelatinous in texture. It starts with a soup based on pork fat, says restaurant group chairman Yang Xiulong, our host for the evening.

"The recipe is 100 years old," he says, leaning forward to confide that "Jackie Chan can eat 10 orders of this dish when he comes here."

Yang's bravado doesn't stop there. He tells us the waxberries are so fresh they were still on the tree in Zhejiang province this morning. The fish head and crab roe soup, he says, is so full of omega-3 goodness that "we are really eating medicine". (With black vinegar, cilantro, spring onion and finished with bean sprouts, it tastes a lot better than any cure-all my doctor would offer.)
