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

  • ginger
  • sage
  • rosemary
  • sage
  • mustard
  • cumin

Additionally from other articles:

  • black pepper
  • mustard seed
  • turmeric
  • cinnamon
  • cardamom
  • cloves

Acids mentioned by others:

  • vinegar
  • citric acid

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.

        I would assume the same is true for honey, since honey is just a solution of sucrose and glucose thats high enough in concentration of those sugars that it won’t mold, but it will if you dilute it
