These are rather typical onion bhajis, but I spice them up with minced chillies. Besan is ground chickpea flour; it's also known as gram flour, and you can find it at Asian shops.
Does it have to be Gram Flour or can you use any? - 21 Feb 2010
this is by far the best recipe i have tried.. the batter seemed thin, but actually worked really well, none of the stodge i've had from other recipes... i didn't have chillis, but they tasted good anyway! - 21 May 2010
Very Tasty and easy to do. Had a bit of trouble finding the right flour by the right name. Ended up with Chana Flour which is Besan which is chick pea. - 30 Dec 2009 (Review from Allrecipes US | Canada)
