How to Tell if Sour Cream is Bad: Expert Tips for Spotting Spoiled Sour Cream
Signs that sour cream has gone bad include mold growth, discoloration, off smell, sharp or bitter taste, curdling, and dryness. Mold growth appears as fuzzy grey or green spots, and a moldy film may also be present. Discoloration indicates bacterial or fungal growth. An off smell beyond the usual tangy aroma suggests spoilage. A sharp, bitter, rancid, or yeasty taste is a sign of spoilage. Curdling is normal if there is a light layer of white, milky liquid on top, but lumps or curdles indicate spoilage. Dryness and no presence of whey (milky, watery liquid) are also signs of spoilage.
Tips for storing sour cream properly:
1. Store sour cream in the fridge below 40°F (4°C) to slow down the growth of molds and bacteria.
2. Store sour cream further back in the fridge for more constant temperature, not in the fridge door.
3. Keep sour cream tightly covered in the original packaging or in a clean airtight container to prevent spoilage.
4. Use clean and dry utensils to scoop out sour cream to avoid cross-contamination.
