Preheat oven to 180'C/Gas mark 4 and heat a pan on medium-high with 1cm oil in it
Put milk into small bowl and add the lemon juice - stir and leave
Mix all the dry ingredients in the large bowl
Toss the chicken in the dry flour mix one at a time, place on the rack
Dip the chicken into the milk/lemon mix (it should be nice and thick now, like cream)
Shake off the excess liquid and place into the flour mix again - shake the bowl, flip over the chicken piece and shake again, take it out and place it back onto the rack
Do this until all of the pieces are coated completely
Fry the chicken 2-3 pieces at a time (don't crowd the pan) until they start to colour (about 2-3 mins each side) and place back onto the rack
When all the pieces are done place the baking tray in the oven for 30 minutes to finish them off, turning over halfway through
For the gravy 1, Pour as much oil out of the frying pan as you can without losing any of the golden flour mix that will no doubt be at the bottom of the pan by now 2, Lower the temperature of the hob to medium low and melt the butter 3, Once the butter has melted remove from the heat and add 1-2 tbsp of flour mix to the pan and stir 4, Cook for 4 minutes - 30 seconds on the hob, 30 seconds off (it keeps the flour from burning) 5, Take the frying pan off the heat and add freshly boiled water a little bit at a time, stirring constantly until you have the gravy at the consistency that you like 6, Turn the gravy down to the lowest setting to keep warm until the chicken is done 7, Serve
