If you’re talking about milk, the problem is often storage temperature rather than the milk itself.
🥛 Help milk stay fresh longer
Keep it in the back of the refrigerator, where the temperature is most stable—not in the refrigerator door.
Keep your refrigerator at 40°F (4°C) or below.
Put milk back in the fridge promptly after pouring; don’t leave it sitting out.
Keep the container closed tightly to prevent odors and contamination.
Don’t pour unused milk back into the original container.
Follow the package’s use-by guidance, and when in doubt about spoiled milk, don’t taste it to test it.
If you meant another food that goes sour too quickly, tell me which one and I’ll give you the best storage trick.
