Adam Ragusea - A novel method for boiling eggs (and a talk about egg prices & public science)
Italian researchers from Naples have introduced a novel egg boiling technique called periodic cooking, inspired by sous vide methods. This approach involves alternating the egg between boiling and cooler water every two minutes for a total of 32 minutes. This method aims to achieve a creamy yolk while ensuring the egg white is solid, addressing the common issue with sous vide eggs where the white remains semi-liquid. The process is labor-intensive, requiring precise timing and temperature control, making it impractical for everyday use without automation. The video also discusses the impact of avian influenza on egg prices in the US, explaining that a significant number of egg-laying hens have been culled, leading to shortages and price increases. Additionally, the video touches on the potential consequences of proposed cuts to publicly funded science in the US, emphasizing the importance of continued investment in scientific research for technological advancement and public health.
Key Points:
- Periodic cooking involves alternating eggs between boiling and cooler water to achieve desired texture.
- The method is labor-intensive and requires precise timing, making it impractical without automation.
- Avian influenza has led to a significant culling of egg-laying hens, causing egg shortages and price hikes in the US.
- Proposed cuts to publicly funded science in the US could severely impact research and technological progress.
- Publicly funded science is crucial for advancements in technology and public health.
Details:
1. 🍳 The Italian Egg Cooking Revolution
- Italian scientists have introduced a novel egg cooking method called 'periodic cooking,' which enhances traditional sous vide techniques by alternating between boiling and cooling to achieve perfect egg texture.
- Sous vide traditionally cooks eggs to have a creamy yolk but often results in a less desirable, semi-solid egg white due to incomplete protein coagulation.
- The periodic cooking technique involves boiling the egg for two minutes, followed by cooling it in room temperature water for two minutes, repeated over a period of 32 minutes.
- This approach is designed to ensure the yolk remains creamy while the egg white is fully solidified, overcoming the limitations of conventional sous vide methods.
- The method relies on mathematical modeling to optimize the cooking process, significantly improving both yolk and white textures for culinary applications.
- This innovative technique not only maintains the benefits of precise temperature control seen in sous vide but also offers a practical solution for achieving uniformly cooked eggs, making it valuable for chefs and home cooks alike.
2. ⏱️ The Art and Science of Periodic Cooking
- Using a sieve to handle half a dozen eggs reduces labor compared to a single egg and slotted spoon, enhancing efficiency.
- Employing a stopwatch with a lap timer ensures precise cooking intervals, reflecting a structured, athletic training-like approach.
- Maintaining water temperature at 100°C is crucial, especially with a weak gas stove, to achieve research-standard results.
- Alternating two-minute intervals between hot and cool water for 32 minutes ensures gradual cooking of egg whites without overheating the yolk.
- Controlling heat transfer is critical to avoid overcooking the egg yolk while ensuring the white is fully cooked.

4. 🐔 The Bird Flu Impact on Egg Prices
- Since 2022, US egg producers have faced an avian influenza outbreak affecting domestic chickens, particularly egg-laying hens, leading to increased egg prices.
- Egg-laying hens are more affected by bird flu compared to chickens raised for meat, necessitating the culling of infected hens to prevent virus spread.
- In recent months, approximately 15% of egg-laying hens were culled, reducing egg supply and causing price increases due to scarcity and panic buying.
- Certain states, such as California, with cage-free egg production laws, have experienced higher bird flu rates, potentially due to migratory bird patterns.
- The economic impact includes not only price increases but also a strain on supply chains, leading to consumer frustration and altered buying habits.
- State-level responses vary; some states have implemented stricter biosecurity measures and quarantine protocols to mitigate further outbreaks.
5. 🐦 Bird Flu and Its Spread to Cattle
- Bird flu can spread to cattle, with cases in the U.S. partly attributed to cattle consuming feed containing pasteurized chicken litter, meant to be germ-free.
- The primary mode of transmission among cattle is through milk, particularly via contaminated milking equipment.
- Human cases of bird flu are mainly among individuals in close contact with birds without proper protective gear, with a few dozen cases and one death in the U.S. over the past year.
- Preventive measures include ensuring feed is free from contamination and enhancing hygiene protocols in dairy production.
- Scientists and public health officials are actively monitoring the situation, though their efforts are increasingly challenged by the spread.
- Additional context: Bird flu, or avian influenza, primarily affects birds but can jump species, posing significant challenges for agricultural and public health sectors.
