Just finished cooking half the Picnic Ham. The full shoulder was 10kg so I cut it in half ~5kg each. Using my composite inject/dry cure method with 500ppm KNO3 for 5 days and my normal smoking time yesterday I allowed the ham to rest in the fridge overnight before cooking today. I put 3 litres of water into the electric cooker and adjusted the thermostat until I got a steady 75 deg C and put the ham in. This was 10 deg lower than my earlier ham but I reasoned as follows:
1 The shoulder joint was from a much larger and older animal
2 It would therefore be much tougher, shoulder usually is
3 Longer cooking would be required to ensure tenderness
4 Lower temperature would preserve succulence during longer cooking
I have completely abandoned the idea of timing the cooking process, it is too hit-and-miss. I have come down firmly on the side of internal temperature with a probe thermometer. It took 9 hours for the ham to reach 72 deg at it's thickest part at which point I switched off the power and waited another 3 hours for it to cool down to 50 deg. I find that insulating the cooker all round with several tea towels greatly reduces the amount of electricity consumed. The whole cooking time barely consumed 2 units.
The results are outstanding. Moist, delicately-flavoured ham. Different to my earlier posting but different doesn't mean inferior. The colour, as expected, is a much deeper pink due to the 500ppm nitrate and all four of the above suppositions were 100% accurate. It is absolutely perfect ham, in my opinion far better than anything I might buy. Pic below.
I have found in the past 18 months of R & D with making Bacon, Ham, Sausage etc. that there is a lot of hype that I thought daunting initially but having chucked all that out of the window I have developed far simpler methods that I hope members will find useful.
All the best,
Vernon
