Storage times and freshness tips for massaman curry paste in different conditions.

Safety first: This guide provides general information. When in doubt, throw it out! Trust your senses and err on the side of caution. If something smells, looks, or tastes off, don't consume it.

unopened pantry
1-2 years past printed best-by date

Signs of Spoilage

Bulging container, visible mold (extremely rare if sealed), unusual strong off-odor detectable through the sealed packaging.

How to Check

Primarily rely on the 'best by' or 'expiration' date. Visually inspect the packaging for any damage, leaks, or signs of pressure (bulging).

Storage Tips

Store in a cool, dark pantry or cupboard, away from direct sunlight, heat sources, and strong odors. The 'best by' date is for peak quality; the paste may still be safe to use for some time after if stored correctly and showing no spoilage signs.

opened fridge
1-3 months

Signs of Spoilage

Visible mold (green, white, black, fuzzy spots) on the surface or sides, significant discoloration (darkening or unusual hues), sour, rancid, yeasty, or 'off' smell, excessive drying out on the surface, or a slimy texture.

How to Check

  1. Visual Inspection: Open the container and carefully look for any fuzzy growth or unusual colors on the surface or sides.

  2. Smell Test: Take a cautious sniff. It should smell aromatic and spicy. If it smells sour, rancid, musty, or otherwise unpleasant, it's likely spoiled.

  3. Texture Check (if visual/smell are okay): Use a clean spoon to check if the paste has become excessively dry and hard, or if there's any sliminess.

Storage Tips

Always use a clean, dry spoon to scoop out paste to prevent introducing contaminants. Ensure the lid is tightly sealed after each use. Some brands recommend adding a thin layer of neutral oil (like vegetable or canola) on top of the paste before sealing to create an oxygen barrier and extend freshness.

freezer
6-12 months

Signs of Spoilage

Significant loss of vibrant aroma and flavor upon thawing, excessive freezer burn (if not sealed properly), or signs of spoilage that were present before freezing.

How to Check

  1. Visual Inspection: Check for excessive ice crystals or signs of drying (freezer burn) on the surface, which indicates a loss of quality.

  2. Smell Test (after thawing): Once thawed, check for the characteristic aromatic smell. If it's bland or has an 'off' odor, quality may have degraded.

Storage Tips

To freeze, portion the paste into ice cube trays, small freezer-safe containers, or spread flat in a freezer bag. Once frozen, transfer cubes/portions to an airtight freezer bag or container. This allows for easy thawing of small amounts. Thaw in the refrigerator overnight, or add directly to your cooking, as it thaws quickly with heat.
