You’re doing it all wrong. Here’s the right way to store milk and dairy

Leftover dairy products such as sour cream, yogurt, or cottage cheese should be stored in airtight containers to prevent exposure to air, which can lead to spoilage. Airtight containers also prevent the absorption of other flavors from the fridge, ensuring your dairy products maintain their intended taste.
7. Maintain a Consistent Fridge Temperature for Optimal Storage
Keeping your fridge at a consistent temperature is crucial for proper dairy storage. The optimum temperature range is between 1°C and 4°C (34°F and 39°F). Regularly check your fridge’s thermostat and adjust as needed to maintain this range. Fluctuating temperatures can lead to faster spoilage of dairy products.
8. Avoid Storing Dairy Next to Strong Odors
Dairy products can easily absorb strong odors from nearby foods, which can alter their taste and aroma. To prevent this, store dairy products away from foods with strong smells, such as onions, garlic, or certain cheeses. Consider using separate storage containers or different shelves for these items.
9. Check Expiration Dates and Rotate Stock Regularly
