What to use instead of koseret
Quick answer
The closest option is Mexican oregano, rated acceptable. The same genus, and the closest herb most cooks can buy. Mexican oregano leads on thymol and carvacrol and is sharper; cultivated koseret leads on linalool and is softer and more floral. The butter will smell herbal and correct in kind, and a little harder than it should.
It will not do for: Gurage kitfo, where koseret is the identifying aroma.
