@Sumaiya - Walaikumsalaam. Yes they certainly can. Bring to room temperature before hearing to avoid over roasting the bun
@Cosmicgirl - For this recipe the magic masala is the main spice, you can use your normal spices like dhana and jeeru to replace but it won’t give the same taste
@Fathima Suleman - Yes it is
@S_k_mansoor - Approximately 24 depending on the size you make.
