Big tick in the box for this one from me!
I got to try it sooner than expected because when I came to portion out the 10 batch of bulk lamb madras I made today I found my precooked lamb was only going to stretch to 8 portions. A quick fry up of G&G, cumin seeds, panch phoran, salt and cumin & turmeric powders & dilute Tom puree and then into the frying pan went some potato chunks.
I didn't really have enough potato to fry for ten mins without it getting too scorchio so I covered my pan with foil and popped it into a low oven at fan 130C for 50 mins. The result was lovely as the spices were nicely roasted and flavoursome and the potato was just right without being overcooked and mushy, as it might easily have been if boiled. I think there was scope to drop down to 120C or 130C/40 mins as the potato would probably still get cooked enough.
I've just polished off the first portion for an early dinner tonight and with a couple of chunks of potato included it was lovely grub. Thanks for the method jb, I can see myself using this plenty in the future.
