According to Modern Cosmetics black cumin seed oil is very unique; they state there is “no suitable substitute”. I would probably choose something like evening primrose oil if a substitution was required.

How to Work with It

Include it in the oil phase of your recipes; it can be hot or cold processed, but if you can avoid heating it that’s probably best.

Stored somewhere cool, dark, and dry, black cumin seed oil should last at least one to two years. I recommend storing it in the fridge.
