The condensate expelled from a condensing boiler is acidic, with a pH between 3 and 4. Condensing boilers require a drainpipe for the condensate produced during operation. This consists of a short length of polymer pipe with a vapour trap to prevent exhaust gases from being expelled into the building.
I used a Hormel 2.5 pound pork shoulder. I brined it for 24 hours and tied it up. I followed the recipe exactly. There was very little fat on this smallish piece of meat when I reduced the temperature from 425 to 325 degrees I brushed maple syrup on the roast.sing a pastry brush, spread the mixture all over the pork shoulder. Set the meat on a rack set into a roasting pan. Roast for 20 minutes, and then reduce the heat to 325 degrees F. Continue to cook until an instant-read thermometer inserted into the shoulder reads 185 degrees F, about 4 hours.
The picnic shoulder cut has less fat and more connective tissue than the Boston butt, meaning it needs long time to make it tender. Most pork shoulder recipes have long cooking times anyway, though, so using a picnic shoulder is fine.ost pork shoulder recipes have long cooking times anyway, though, so using a picnic shoulder is fine.
