Today I started to cook the 3L Bangladeshi base gravie from Julian?s ebook.
To my horror and after two and half hours cooking there was a brown residue stuck to the bottom of the pan. I thought this could be the burnt ginger and garlic paste but the other ingredients were not stuck to the bottom of the pan and with a bit of effort managed to get the residue off.

The curry was darker than normal but I have been using a darker onion bhaji oil. I was going to throw it away but decided to put the tomato in and give it a wiz and taste it and then make my mind up.
I was thinking that it would taste bitter but it does not at all and does not taste burnt and I would say it tastes better than the ones I did before which was about 3 x 1.5L and one 750ml
Have you guys ever had this and if so what would you do as it's cost me 6 onions costing ?2 and other ingredients?

Have you ever had a brown/black sticky stuff stuck to the bottom when you have been doing yours.
