we use to have a group of people who made homemade syrup in somers,
wi
people would go around collecting sap, and freezing it till we were ready to boil. then we had a large wood fired boiler we used. i wouldnt call it a pot because it was a stainless steel tank, specifically modified for this purpose.
we would start about 800am one day, party all night while boiling 100's of gallons of sap, and have a huge pancake breakfast the next morning. the guys who set it all up would take some of the previous years syrup and use it in homemade sausage for the breakfast. it was a great time.
unfortunitly, the guy who organized and made everything happen quit doing it. looks like no syrup this year. his wife would get so upset with him partying and all the time he put into it that he finally gave up. to be fair though he was like obsessed with making the stuff. it was like liquid gold to him. she probably had good reason to get upset.
