Signs of Spoilage
Visible mold growth (often green, white, or black fuzzy spots on the surface or sides), significant discoloration (darkening or unusual color changes), a sour, fermented, yeasty, or otherwise unpleasant 'off' smell, or an unusually dry/hard or excessively watery texture.
How to Check
-
Visual Inspection: Look closely for any signs of mold. Check for significant changes in color.
-
Smell Test: Open the container and take a careful whiff. It should smell spicy and aromatic. If it smells sour, musty, or unpleasant, it's likely spoiled.
-
Texture Check: Use a clean spoon to check the consistency. If it has become excessively dry and hard, or unusually watery, it's a red flag.
Storage Tips
Always use clean utensils when scooping out harissa to prevent introducing bacteria. Ensure the lid is tightly sealed after each use. Some harissa pastes may develop a thin layer of oil on top; this is normal and can help preserve the paste, but excessive separation with a watery layer underneath could be a sign of spoilage.
freezer6-12 months (for best quality)
Signs of Spoilage
While safe indefinitely from a microbial standpoint when properly frozen, quality degrades over time. Signs include significant freezer burn (dry, discolored spots), or a noticeable loss of flavor and potency after thawing.
How to Check
-
Visual Inspection: Check for excessive freezer burn.
-
After Thawing: Once thawed, check for its characteristic aroma and taste a small amount if visual and smell tests are satisfactory. If the flavor is noticeably bland or 'off', its quality has degraded.
Storage Tips
For best results, portion the harissa paste into smaller, airtight containers, freezer-safe bags, or even ice cube trays (then transfer frozen cubes to a bag) before freezing. This allows you to thaw only what you need. Label with the date. Thaw in the refrigerator overnight before use.
unopened pantry12-18 months (or until 'best by' date)
Signs of Spoilage
Swollen container, bulging lid, leaks, unusual separation beyond normal oil/liquid separation, mold growth (if seal is compromised), or a distinctly 'off' or sour smell.
How to Check
Check the 'best by' or 'expiration' date. Visually inspect the container for any damage, swelling, or leaks. If it's a jar, ensure the safety button on the lid is still depressed, indicating a vacuum seal. If the seal is broken or compromised, it may be spoiled.
Storage Tips
Store in a cool, dark place away from direct sunlight and heat to maintain quality and extend shelf life.
