EMILY FENG, BYLINE: Chef Peter begins his working day at 2 p.m., mixing collectively the garlic, ginger, soy sauce, sugar and a boatload of spices that type the foundation of his cuisine. Then he meticulously unwraps a plastic bag with his mystery component. It is really a sauce which is 40 decades outdated.

PETER: (Through interpreter) This is just a person small element, but it can be vital to the over-all taste.

FENG: The sauce is referred to as Lu or Lu Shui. And fundamentally every Chinese regional cuisine uses some variation of it. Ordinarily it can be designed out of a base of salt, these types of as soy sauce, sugar and a mix of spices. And to Peter, the sauce is a residing, respiratory detail.

PETER: (By interpreter) You have to elevate an outdated Lu sauce like raising a child.

FENG: You may possibly be wondering by now – the sauce is not basically 40 years aged, but it will come from an unbroken chain of sauces dating back to the to start with a person his mom in Shanghai designed in the 1980s. Peter often saves the remainder of each individual Lu batch and uses the previous sauce to commence the future new batch of sauce. It really is a bit like sourdough, in which the outdated seeds the new and the taste intensifies more than the years. This is the way most Lu sauces are created.

PETER: (By way of interpreter) Believe about it. In one particular dish of Lu-braised duck, you happen to be taking in the essence of at the very least 7,000 or 8,000 ducks that have handed through it.

FENG: Once, an unknowing waiter threw out the Lu sauce Peter was conserving for the upcoming day’s dishes.

FENG: Cao Yu, a food stuff author and historian at Jinan College, says Lu at initial only denoted any form of salt water utilised as a marinade for chilly boiled meat and veggies.

CAO YU: (Via interpreter) I feel the emergence of the Lu we know right now is about by the Ming dynasty, additional than seven hundreds of years back, when you observed the emergence of privatized companies and marketplaces.

FENG: To attract new customers, these new personal food vendors started introducing new flavors and new strategies to cook dinner Lu, by adding spices or soy sauce for color. In the generations because, Lu has diversified, using on the characteristics of each and every regional delicacies. For case in point, in spicy Sichuan province…

YU: (By interpreter) Lu is utilised to incorporate flavor and depth. So Sichuanese use a ton of spices in their Lu. But in Cantonese cooking, they want the taste of the ingredients to come out. So they use far significantly less salt and spice.

FENG: Some Lu is even alcoholic, like Zao Lu, a light-weight marinade created from the fermented glutinous rice mash still left more than from brewing Chinese yellow wine, or huangjiu.

FENG: 4 several hours afterwards in Peter’s kitchen area, his significantly sweeter Shanghai-design and style Lu has simmered down to a dim, thick soup. Peter minimizes it even further until eventually it will become a molasses-like syrup.

PETER: (Via interpreter) The sauce coats each morsel. The juices combine evenly with the unwanted fat of the pig trotters in this circumstance.

FENG: The intensive aged Lu sauce is what is made Peter’s restaurant a perfectly-hidden gem in Beijing by phrase of mouth only. In actuality, Peter expressly forbade us from making use of his total identify or mentioning his cafe in this piece for the reason that he does not want also lots of consumers

PETER: (By interpreter) We have a expressing – fame brings issues (laughter). And this cafe is my playground. I never want far too a lot of individuals to occur.

FENG: Cooking every evening is also a very little dangerous. Peter says he goes all-in each time, utilizing up all his outdated Lu sauce for pork, beef and duck for each and every evening meal – no backups, no insurance policy.

(SOUNDBITE OF Foods Sizzling)

PETER: (By way of interpreter) We are extremely cautious – very mindful with the sauce.

FENG: I inquire about vacations. Would he ever entrust a different human being to feed and consider treatment of his Lu sauce if he’s away? No, Peter says. The sauce is just also significant to him.
