Dass met Gursikhs in India who do Sangat with Pooran jee and Singhs. Gursikhs there said that Kurmaai is not needed and according to Gurmat for Gursikhs. It is a mere waste of time ritual.
I know they shaak laddo or barfi in Darbaar Sahib for Kurmaai, this is not allowed in Darbar Sahib as only Degh can be consumed in Deevan.
Can Sangat here please give reasons for no Kurmaai.
Below I found brief explanation on Kurmaai's, seems a bit pointless on the whole.
The Kurmai ceremony, which can take place months before the wedding or just before the Anand Karaj (marriage ceremony). It is the equivalent to the chunni ceremony in that the girl’s family comes to the boy’s house or gurdwara where the boy’s family have held a paath (prayer). They will invite their family and friends. Traditionally, only men from the girl’s family would come but now anyone comes, except the girl – who is not meant to go to her in-laws before marriage, at least that is the traditional custom!
