EMILY FENG, BYLINE: Chef Peter commences his day at 2 p.m., mixing together the garlic, ginger, soy sauce, sugar and a boatload of spices that variety the foundation of his cuisine. Then he thoroughly unwraps a plastic bag with his mystery ingredient. It is really a sauce that is 40 decades outdated.
PETER: (By interpreter) This is just a single compact element, but it really is very important to the over-all style.

Normally it can be made out of a base of salt, these types of as soy sauce, sugar and a combine of spices. And to Peter, the sauce is a dwelling, breathing factor.
PETER: (By means of interpreter) You have to increase an outdated Lu sauce like increasing a baby.
FENG: You may possibly be wondering by now – the sauce is not actually 40 years outdated, but it will come from an unbroken chain of sauces relationship back to the initial a person his mom in Shanghai produced in the 1980s. Peter generally will save the remainder of each individual Lu batch and takes advantage of the previous sauce to get started the subsequent new batch of sauce. It truly is a bit like sourdough, where by the aged seeds the new and the taste intensifies in excess of the decades. This is the way most Lu sauces are manufactured.
PETER: (By means of interpreter) Assume about it. In just one dish of Lu-braised duck, you’re consuming the essence of at the very least 7,000 or 8,000 ducks that have handed via it.
FENG: When, an unknowing waiter threw out the Lu sauce Peter was conserving for the up coming day’s dishes.

FENG: Cao Yu, a foodstuff writer and historian at Jinan College, says Lu at initial simply just denoted any kind of salt drinking water applied as a marinade for chilly boiled meat and veggies.
CAO YU: (Via interpreter) I think the emergence of the Lu we know today is around by the Ming dynasty, far more than 7 hundreds of years in the past, when you noticed the emergence of privatized enterprises and marketplaces.
FENG: To bring in new consumers, these new non-public food sellers started introducing new flavors and new methods to cook Lu, by introducing spices or soy sauce for shade. In the centuries due to the fact, Lu has diversified, having on the traits of each individual regional delicacies. For case in point, in spicy Sichuan province…
YU: (By interpreter) Lu is utilized to increase taste and depth. So Sichuanese use a ton of spices in their Lu. But in Cantonese cooking, they want the flavor of the ingredients to arrive out. So they use considerably fewer salt and spice.
FENG: Some Lu is even alcoholic, like Zao Lu, a light-weight marinade manufactured from the fermented glutinous rice mash remaining in excess of from brewing Chinese yellow wine, or huangjiu.

FENG: Four hours later on in Peter’s kitchen, his much sweeter Shanghai-style Lu has simmered down to a dark, thick soup. Peter minimizes it even further until finally it will become a molasses-like syrup.
PETER: (As a result of interpreter) The sauce coats each individual morsel. The juices combine evenly with the unwanted fat of the pig trotters in this case.
FENG: The powerful old Lu sauce is what is actually built Peter’s cafe a perfectly-concealed gem in Beijing as a result of phrase of mouth only. In fact, Peter expressly forbade us from utilizing his comprehensive title or mentioning his cafe in this piece due to the fact he does not want far too many prospects
PETER: (Via interpreter) We have a declaring – fame delivers problems (laughter). And this cafe is my playground. I you should not want too several folks to come.
FENG: Cooking each individual night is also a minor risky. Peter suggests he goes all-in each individual time, utilizing up all his outdated Lu sauce for pork, beef and duck for just about every meal – no backups, no coverage plan.
(SOUNDBITE OF Food stuff Sizzling)
PETER: (Via interpreter) We’re extremely mindful – exceptionally watchful with the sauce.
FENG: I question about holidays. Would he at any time entrust a further particular person to feed and get care of his Lu sauce if he’s away? No, Peter says. The sauce is just too essential to him.
