Hi Mick, I had been using the 'water based method' for quite some time, until I tried the 'Glasgow method' which basically replaces the water with oil (plus the spices) The outcome was excellent and kept the chicken (or Lamb/mutton) nice and succulent, and the leftover oil doesn't go to waste as it makes an excellent seasoned oil. I find the water method can draw the flavour out of the meat, afterall that's how a good stock is made.
What's your thoughts on this, have you tried both methods?
Cheers,
Ken
