Why Jodhpur loves so much besan?

I am from Uttar Pradesh working here in Jodhpur. Next month, I will complete 1 year in Jodhpur. One thing, that I love is food... lots of food. Now, what I have seen here, people love eating besan so much...like gatte ki sabji, Sev tamatar, mirchi vada, everything has besan in it. So, why do Jodhpur loves so much besan? Also, there are stalls of panipuri, dahi Puri, sevpuri everywhere but why not aaloo tikki, aaloo chat, samosa and all?
