1 of the wonderful cornerstones of Chinese culture is its foodstuff. And at the coronary heart of China’s lots of regional cuisines is just one top secret sauce. NPR’s Beijing correspondent Emily Feng brings us into a kitchen to discover what it is.

EMILY FENG, BYLINE: Chef Peter commences his day at 2 p.m., mixing jointly the garlic, ginger, soy sauce, sugar and a boatload of spices that kind the base of his delicacies. Then he meticulously unwraps a plastic bag with his mystery component. It is a sauce that’s 40 several years aged.

PETER: (By means of interpreter) This is just a person small component, but it is essential to the total flavor.

FENG: The sauce is called Lu or Lu Shui. And fundamentally each Chinese regional cuisine employs some variation of it. Normally it’s created out of a foundation of salt, this sort of as soy sauce, sugar and a mix of spices. And to Peter, the sauce is a dwelling, respiration matter.

PETER: (By interpreter) You have to elevate an aged Lu sauce like elevating a kid.

FENG: You could possibly be wondering by now – the sauce is not practically 40 decades old, but it comes from an unbroken chain of sauces relationship back to the first just one his mom in Shanghai designed in the 1980s. Peter generally will save the remainder of every single Lu batch and uses the old sauce to get started the upcoming new batch of sauce. It’s a little bit like sourdough, exactly where the aged seeds the new and the taste intensifies above the a long time. This is the way most Lu sauces are designed.

PETER: (Through interpreter) Feel about it. In one dish of Lu-braised duck, you might be ingesting the essence of at the very least 7,000 or 8,000 ducks that have passed through it.

FENG: When, an unknowing waiter threw out the Lu sauce Peter was saving for the up coming day’s dishes.

PETER: (As a result of interpreter) I fired him. People who are in the company know that this Lu is like my lifetime. And it is really a very little element of my mom. So throwing it away is like disrespecting my ancestors’ tombs.

FENG: Cao Yu, a meals writer and historian at Jinan College, claims Lu at 1st simply just denoted any sort of salt h2o utilized as a marinade for chilly boiled meat and veggies.

CAO YU: (By way of interpreter) I imagine the emergence of the Lu we know now is about by the Ming dynasty, a lot more than 7 centuries back, when you observed the emergence of privatized firms and markets.

FENG: To draw in new consumers, these new private food items sellers commenced introducing new flavors and new methods to prepare dinner Lu, by incorporating spices or soy sauce for color. In the hundreds of years considering that, Lu has diversified, taking on the qualities of just about every regional cuisine. For instance, in spicy Sichuan province…

YU: (As a result of interpreter) Lu is utilized to add taste and intensity. So Sichuanese use a ton of spices in their Lu. But in Cantonese cooking, they want the flavor of the ingredients to occur out. So they use considerably a lot less salt and spice.

FENG: Some Lu is even alcoholic, like Zao Lu, a gentle marinade produced from the fermented glutinous rice mash remaining above from brewing Chinese yellow wine, or huangjiu.

FENG: Four hrs later in Peter’s kitchen area, his substantially sweeter Shanghai-model Lu has simmered down to a dim, thick soup. Peter lowers it more until it gets a molasses-like syrup.

PETER: (By interpreter) The sauce coats each morsel. The juices combine evenly with the fats of the pig trotters in this situation.

FENG: The rigorous outdated Lu sauce is what is actually manufactured Peter’s restaurant a nicely-hidden gem in Beijing through term of mouth only. In truth, Peter expressly forbade us from applying his full identify or mentioning his cafe in this piece because he does not want far too several buyers

PETER: (Through interpreter) We have a indicating – fame provides difficulties (laughter). And this restaurant is my playground. I never want much too a lot of men and women to arrive.

FENG: Cooking every single night is also a very little risky. Peter claims he goes all-in each individual time, using up all his old Lu sauce for pork, beef and duck for each and every dinner – no backups, no insurance plan plan.

(SOUNDBITE OF Foods Sizzling)

PETER: (By way of interpreter) We are really careful – incredibly very careful with the sauce.

FENG: I check with about holidays. Would he ever entrust yet another individual to feed and just take care of his Lu sauce if he is absent? No, Peter says. The sauce is just too significant to him.
