I watched this YouTube video yesterday on Bengali Shatkora Curry.

She cut it into wedges and sat it to char roast over a lit gas burner on her hob. She says it removes the bitterness, strengthens the aroma and releases and improves the flavour. This curry could be similar to what CT has posted above, albeit more traditional in style. I wonder if the same technique works on lemons and limes. I imagine it would do. I microwave lemons before juicing to release more juice.
