Besan is made from Bengal Gram (Kala Chana, dark brown skin), not from Chickpeas (garbanzo 'beans' or Chana, cream color skin). The whole seeds are roasted lightly and milled to a flour. ... 'Chickpea flour', though a misnomer, is the accepted English name for Besan. A coarse form of black gram flour is known as Sattu.
