Sauerkraut in freezer by mistake is it still okay to cook with?

Here's why:

* Sauerkraut is already fermented: The fermentation process involves lactic acid, which acts as a natural preservative. This makes sauerkraut less susceptible to spoilage compared to fresh cabbage.

* Freezing doesn't necessarily ruin it: While freezing can change the texture of sauerkraut, making it softer and less crisp, it doesn't necessarily make it unsafe to consume.

* Taste and texture might be affected: The texture will likely be softer and the flavor may be slightly altered. You might notice a bit more liquid as well.

Here's what to do:

1. Inspect the sauerkraut: Check for any signs of mold, discoloration, or off-putting smells. If you notice any of these, it's best to discard it.

2. Taste a small amount: Before using the sauerkraut in your recipe, taste a small amount to see if the flavor is acceptable.

3. Adjust your recipe: If the taste and texture have changed, you might need to adjust the recipe accordingly. For example, you might need to add more liquid or spices to compensate for the softer texture.

Overall, it's probably safe to use frozen sauerkraut in your cooking, but be aware that the texture and flavor might be altered.
