If you incorporate these ingredients in your cooking, your left-overs will last longer:

  • honey
  • salt
  • garlic

  • rosemary
  • sage
  • mustard
  • cumin

Additionally from other articles:

Acids mentioned by others:

  • lemon/lime juice

I just had some harissa get moldy after just a couple weeks in a jar in the fridge. I was surprised. I suppose it implies a lack of the above ingredients.

    Adding sugar in low amounts to food will make it spoil faster. Sugar is only a preservative at high sugar concentrations to prevent bacterial growth.

    Notably missing from this lists are acids: lemon juice, vinegar, citric acid which will lower ph and slow bacterial growth.
