What can you do with expired or sour milk? Don’t throw it away yet!

  • Add 1–2 cups of sour milk to a warm bath.
  • Optional: Add a few drops of essential oil or dried flowers.
  • Soak for 15–20 minutes for softer, smoother skin.

🍽️ 6. Cook Savory Dishes

Use slightly sour milk in creamy or savory dishes where the tangy flavor won’t be out of place.

Try adding it to:

  • Mashed potatoes (replaces regular milk)
  • Creamy soups or chowders
  • Savory pancakes or fritters

🚫 When to Toss It

If the milk:

  • Has visible mold
  • Smells rotten or putrid
  • Is clumpy or slimy
  • Has separated completely

➡️ Don’t risk it—throw it away. These are signs it’s gone beyond sour and is no longer safe.
