Having taken my class of children to visit a local gurdwara and wishing myself to learn more about your faith, I would like to attend on a Sunday at the lovely gurdwara we visited. My question: would it be acceptable for me to contribute my own cake/dish to be shared at langar? This would be home-cooked (and with many home-grown ingredients). It would be prepared out of the respect and thanks I have for the wonderful sikh community which welcomed us so freely and lovingly, while providing such a rich educational experience to us all; adults and children alike; when we visited the gurdwara.
Many thanks for reading this message and hopefully giving me guidance!
