Ingredients
  

  • Mayonnaise-based bottles ranch, Caesar, Italian
  • Oil-and-vinegar vinaigrettes balsamic, lemon

Method
 

  1. Sniff Test: Give the dressing a quick whiff. Yeasty, sour or “wet cardboard” odors mean it’s time to say goodbye.
  2. Visual Inspection: Shake the bottle. If oil floats on top without recombining, or you spot bubbles and discoloration, discard.
  3. Flavor Check: Taste a tiny bit. Overly bitter, stale or excessively vinegary and greasy flavors are spoilage red flags.
  4. Shelf-Life Guidelines: Unopened, store-bought dressings last up to one year in the pantry. Once opened, refrigerate and use within two months.
  5. Homemade Dressings: Dairy-free vinaigrettes stay fresh up to two weeks; creamy, mayo-based dressings last 3–5 days. When in doubt, toss it out.
