What to use instead of blue fenugreek
Quick answer
The closest option is Fenugreek with Coriander seed, rated acceptable. Different species of the same genus, and the difference is one of degree so large that it becomes a difference of kind. Blue fenugreek is Trigonella caerulea and is made from the dried flowering tops rather than the seed, which makes it mild, nutty and gently bitter. Common fenugreek seed is Trigonella foenum-graecum and is aggressive, burnt-sugar sweet and bitter enough to spoil a dish at three times the dose. Cutting it back and adding coriander seed approximates the mildness and the citric lift.
It will not do for: Any dish where blue fenugreek is used generously, since common fenugreek at that volume is inedible; Ajika and other mixtures where the herb balance is the whole recipe.

Fenugreek with Coriander seed
AcceptableUse: ~0.35× by volume — About a third of the volume in common fenugreek, made up with ground coriander seed. The reduction is the important part: common fenugreek is far stronger and measuring one for one is the usual way this goes wrong.

Works for
- Khmeli suneli made at home, where it is one of many herbs
- Georgian walnut sauces, where the nutty note is what is wanted
Does not work for
- Any dish where blue fenugreek is used generously, since common fenugreek at that volume is inedible
- Ajika and other mixtures where the herb balance is the whole recipe
Cuisine: Blue fenugreek is one of the few ingredients that identifies a dish as Georgian rather than broadly Caucasian. Substituting it produces something in the right region and not in the right country.
Why there is no second option: Common fenugreek is the same genus and is the only plant that is. Nothing else carries sotolon, the compound responsible for the burnt-sugar note both species share, so no unrelated herb approaches it — celery leaf and lovage were considered for the savoury bitterness and have no fenugreek character at all. The problem with the only option is that it is three times too strong, which the ratio handles and which is why this remains an approximation. Editorial judgement.
Sold as utskho suneli in Georgian shops and increasingly online. Worth buying, because the substitution above is a poor imitation of a cheap spice.
