Manab: here it is Til ( Sesame) and some jeera ( cumin seed) roast in a pan, and grind it in the blender, If it is not too much believe me it will grind really well, add pakeko( roasted) golbheda, hariyo Khursani, noon, lasun, Adua and gind all together. Your Achar for mom will be ready. Well, you do not have to add all the things, you can avoid some things. Enjoy your momo achar.
