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

honey
salt
garlic
sugar (only in high amounts according to feedback; small amounts shortens the life)
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
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.

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

i wondered about that.
