Fenugreek substitution
For the seeds, substitute 1 tsp fenugreek seeds with 1 tsp yellow mustard seeds.
For the leaves, substitute 1 Tbs chopped fresh fenugreek leaves with:
1 tsp dried fenugreek leaves
1 Tbs chopped fresh Chinese celery leaves
1 Tbs chopped frehsh celery leaves
1 Tbs chopped watercress leaves
Fenugreek, if being used for cooking, has a sweet flavor. It is used in artifical maple flovoring. I think it has an odor like maple syrup, but is also close to fennel bulb and seed.
