Storage Tips

Refrigeration

You should always keep half-and-half in the refrigerator to maintain its freshness and safety. Place it in the coldest part of your fridge, not the door, because the temperature stays more stable there. After each use, seal the container tightly and return it to the fridge right away. Clean hands and utensils help prevent bacteria from getting inside. Follow these best practices:

• Store half-and-half at 40°F or below.

• Keep it in its original, tightly sealed container.

• Use the oldest carton first.

• Avoid leaving it out after pouring.

Consistent refrigeration helps Half-and-Half Last up to 7 to 10 days after opening. Always check the printed date for best results.

Freezing Advice

Freezing half-and-half is not a good idea if you want to keep its creamy texture. When you freeze it, the milk fat and water separate. This can make the liquid grainy and thin after thawing. You might notice a change in taste, too. While you can use thawed half-and-half in baked goods or coffee, it will not work well in sauces or recipes that need a smooth texture. If you do freeze it, use the thawed product within 24 hours and keep it cold to stay safe.

Room Temperature

Half-and-half should not sit out at room temperature for long. At temperatures up to 90°F, you can leave it out for only 2 hours. If the room is hotter than 90°F, limit the time to 1 hour.

Leaving half-and-half out too long lets bacteria grow. This can cause foodborne illness, with symptoms like stomach pain or nausea. Always return it to the fridge quickly to keep it safe and fresh.

Visual Clues

If you see any of these, do not use the product. Even if the date on the carton says it should still be good, these clues mean it is no longer safe.
