Quick Summary: No, century eggs are not made with horse urine. This is a common myth! Century eggs are made by preserving duck, chicken, or quail eggs in a mixture of clay, ash, salt, quicklime, and rice hulls for several weeks or months. The alkaline mixture cures the egg, changing its flavor and texture.
Ever heard a weird rumor about food that just makes you go, “Ewww, really?” The story about century eggs being made with horse urine is one of those! It’s a pretty common myth that makes a lot of people hesitant to even try them. But don’t worry, the real process is a lot less… well, urine-y. We’ll walk you through exactly how these eggs are made, so you can know the truth and maybe even give them a try. Let’s crack this myth and get to the bottom of it!
What Exactly is a Century Egg?
A century egg (also called pidan, thousand-year egg, or millennium egg) is a Chinese delicacy. But don’t let the name fool you! They aren’t actually a century old. The name comes from the long curing process they undergo. The result is a truly unique food with a dark, gelatinous egg white and a creamy, strong-flavored yolk.
A Brief History
The history of century eggs goes back centuries, with some stories tracing it back to the Ming Dynasty. The legend says that someone accidentally discovered them in mud. While we can’t be sure about the exact origin, it’s clear that this method of preserving eggs has been around for a very long time.
What Does a Century Egg Look and Taste Like?
Okay, let’s talk about the appearance. The egg white turns into a dark brown or even black, translucent jelly. The yolk goes dark green or grey and has a creamy texture. The taste? Well, it’s an acquired one! It’s often described as having an ammonia-like aroma with a rich, savory, and slightly cheesy flavor.
The Real Process: How Century Eggs Are Made
Forget the horse urine rumors. Here’s the real deal on how century eggs are made:
- Selecting the Eggs: Fresh duck, chicken, or quail eggs are typically used. The quality of the eggs matters for the final product.
- Mixing the Curing Paste: This is where the magic (and science) happens. The traditional mixture usually includes:
- Clay
- Ash (from burned wood or rice husks)
- Salt
- Quicklime (calcium oxide)
- Rice Hulls (optional, for coating)
- Water
- Coating the Eggs: The eggs are carefully coated in the paste. This needs to be done evenly to ensure proper curing.
- Curing Time: This is the long game. The eggs are placed in large jars or containers and left to cure for several weeks or even months. The length of time affects the flavor and texture.
- Cleaning and Packaging: After curing, the eggs are cleaned, often coated in rice hulls to prevent sticking, and then packaged for sale.
The Science Behind the Transformation
So, how does this mixture change the egg? The key is the alkaline nature of the ingredients. The quicklime increases the pH of the egg. This process breaks down the proteins and fats, leading to the unique texture and flavor of the century egg.
Why the Horse Urine Myth?
Okay, so if century eggs aren’t made with horse urine, where did that idea come from? There are a few possible reasons for this misconception:
- Appearance: The dark color and strong smell of century eggs can be off-putting to some. This might lead to people jumping to conclusions about how they’re made.
- Misunderstandings: Language barriers and cultural differences can lead to misunderstandings about traditional food preparation methods.
- General Gross-Out Factor: Let’s be honest, the idea of using urine in food is just inherently gross. Sometimes, sensational rumors spread because they’re shocking.
Debunking the Myth: Why Horse Urine Wouldn’t Work
Let’s think about this logically. Using horse urine to make century eggs wouldn’t actually work for a few reasons:
- Not Alkaline Enough: Horse urine isn’t alkaline enough to cause the chemical changes needed to transform the egg. The quicklime is essential for raising the pH.
- Contamination Risk: Using untreated urine would introduce a high risk of bacterial contamination, making the eggs unsafe to eat.
- Unpleasant Taste: Even if it did work, the resulting egg would likely taste terrible!
Century Egg Nutrition and Safety
Now that we know how they’re made, let’s talk about nutrition and safety:
Nutritional Value
Century eggs do have some nutritional value. They contain protein and some minerals. However, the curing process does alter the nutrient content compared to a fresh egg.
| Nutrient | Approximate Amount (per egg) |
|---|---|
| Protein | 6-7 grams |
| Fat | 8-9 grams |
| Calcium | 25-30 mg |
| Iron | 1-2 mg |
Potential Health Concerns
The main health concern with century eggs is the potential for lead contamination. Traditionally, lead oxide was sometimes added to the curing mixture to speed up the process. However, this practice is now largely discouraged due to health concerns. Reputable manufacturers now use zinc oxide instead.
When buying century eggs, look for brands that are certified lead-free. Also, moderation is key. Eating them occasionally is fine, but don’t make them a staple of your diet.
How to Eat and Enjoy Century Eggs
Okay, so you’re feeling brave and want to try a century egg. Here are some tips on how to enjoy them:

- Slice or Wedge: Cut the egg into slices or wedges.
- Pair with Flavors: Century eggs are often eaten with pickled ginger, soy sauce, or vinegar. The strong flavors complement the egg’s unique taste.
- In Congee: A popular way to eat them is in congee (rice porridge). The egg adds a savory flavor to the mild porridge.
- Tofu: Another popular way is paired with silken tofu, sesame oil, and soy sauce.
