⚠️ Eating spoiled dairy is one of the most common causes of food poisoning at home.
Fridge
34-40°F (1-4°C)
Cover with water and store in airtight container. Keep refrigerated.
Dairy products require consistent cold storage (40°F or below) to prevent spoilage. A refrigerator thermometer (Amazon) helps ensure your refrigerator maintains safe temperatures.

365 days
Off odor, unusual color, membrane breakdown
Transferring opened dairy into an airtight container (Amazon) can reduce odor absorption and moisture exposure.
Baking, custards, sauces
Whole eggs, egg substitute
The expiration date on raw egg yolks refers to the date until which they are safe to consume. Beyond this date, there is an increased risk of bacterial contamination. However, the best quality of raw egg yolks is typically within 2-4 days of purchase. While they may still be safe to consume after this time, their freshness, flavor, and texture may deteriorate.
To determine if raw egg yolks have gone bad, look for any changes in color or consistency - a fresh yolk should be bright yellow and thick. Smell the yolk for any off-putting odors, as a rancid smell indicates spoilage. Lastly, feel the yolk to ensure it is smooth and not slimy or grainy, both of which are signs of spoilage.
Raw egg yolks, like raw eggs in general, can pose a risk of Salmonella contamination. Salmonella is a type of bacteria that can cause food poisoning, resulting in symptoms such as fever, diarrhea, and abdominal cramps. It is especially important to be cautious when consuming raw egg yolks, especially for individuals with weakened immune systems, pregnant women, young children, and the elderly.
To store raw egg yolks, it is best to separate them from the egg whites and place them in an airtight container in the refrigerator. Adding a little sugar or salt to the yolks can help preserve them. Another pro tip is to cover the yolks with water before sealing the container, as this can help prevent them from drying out. It is important to use the raw egg yolks within a few days for optimal freshness and safety.
Raw egg yolks are a key ingredient in many culinary traditions around the world. They are used in dishes such as mayonnaise, custards, pasta carbonara, and certain desserts. In some cultures, raw egg yolks are even consumed raw as a delicacy or added to drinks for a creamy texture. Additionally, egg yolks are rich in nutrients such as vitamins A, D, E, and K, as well as essential fatty acids.
Raw Egg Yolks can be stored safely in the fridge for up to 2 days. Consuming them after 3 days increases the risk of bacterial contamination and foodborne illness. It's best to discard them if they have exceeded the recommended shelf life.
Raw Egg Yolks should not be left at room temperature for more than 2 hours. After this time, harmful bacteria can multiply rapidly, increasing the risk of foodborne illness. It's crucial to refrigerate Raw Egg Yolks promptly to maintain their safety.
The type of container used to store Raw Egg Yolks can impact their shelf life. Airtight containers are best to prevent contamination and maintain freshness. Avoid storing Raw Egg Yolks in containers that may leak or allow for exposure to air, as this can accelerate spoilage.
