It is best to use pure salt - non iodised and without anti-caking agent. "Table" salt is always iodised so coarse cooking salt is the one you want - as fine cooking salt usuaslly contains an anti-caking agent. You need to read the label. I use a course sea salt.
Yes the figures from the DDF calculator are good.
I use 10g of pepper for 1 to 1.5 Kg pork.
I pop all of the salt, sugar, cure, spice etc into an electric coffee grinder and blitz to a powder. This ensures that it is evenly mixed too.
Yes cure them individually (or in one single lump). You need the cure to diffuse evenly throughout the meat. In individual bags this will happen so long as it is fairly level and any brine produced is in contact with the meat. If you have two pieces of meat and all the brine flows to one end you could get one piece with more cure and the other with less. They should not take up any more space in the fridge as you want to get as much air out of the bags as possible to keep the bag/brine mix in intimate contact with the meat. I actually vac pack mine during the cure.
I have the ProQ smoke generator but, being honest, I prefer to use my
AMNPS. With the ProQ the length of burn will depend on several factors including the type of dust, the moisture content of the dust and the air temperature. It should last 6-8 hours - maybe longer. If you set it going at say 9pm and then go out again at 6am you should be fine. You could always get it going at 6pm and then monitor the burn. If you dont think it will last then top it up again at 11pm before going to bed.
To get it going some use a tea light candle and others use a small cooking brulee gas torch. I just use my Mapp Gas brazing torch. If it does go out unexpectedly then don't panic. Just light it again and carry on. The salt, sugar and cure has already done its job and has made the bacon surface a pretty hostile place for bacteria and mold to grow - and the smoke will have added to this.
To help the dust stay alight, nuke it for a couple of minutes on full power in the microwave before using it.This will get rid of a lot of the moisture content.
