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

Opening multiple cartons of milk at once leads to quicker spoilage as each carton is exposed to air and potential contaminants. To prevent this, ensure you finish one carton completely before opening another. This practice minimizes waste and ensures each carton of milk is consumed while still fresh.
5. Keep Butter in a Sealed Container to Preserve Freshness
Butter can absorb odors and flavors from other foods in the fridge. To prevent this, store butter in a sealed container. This not only helps maintain its flavor but also prevents it from becoming rancid. A butter dish with a lid or a resealable plastic container works well for this purpose.
6. Use Airtight Containers for Leftover Dairy Products
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
