Expiration & Storage Tips
When does harissa expire?
Unopened, harissa paste can last for up to 2-3 years if stored properly, often outlasting the date on the package. Once opened, it should be used within 3-4 months for optimal freshness. If homemade, it's best to use within a week or so. While not commonly frozen, you can freeze harissa for up to six months, though it may lose some texture and flavor.
How do you tell if harissa is bad?
A good rule of thumb is to check the look, smell, and taste. Harissa that has gone bad often has mold, an off smell, or a sour taste. It can also darken in color from a vibrant red to a dull brown. If you notice any of these things, it's best to discard the paste.
Tips for storing harissa to extend shelf life
• Store harissa in the fridge after opening, with the lid tightly sealed.
• Use a clean spoon every time you scoop out paste to prevent bacteria from entering the jar.
• If you made a large quantity, consider freezing some in ice cube trays for easy, portioned use.
