I finally got my act together today, got the propane burner going in my back yard, and boiled down 3 gallons of sap to make about 8 oz. of what I think is syrup.

I'm using a 5 gallon stainless steel pot to do the boiling, and it sure takes a long time. My lab thermometer was reading 220 degrees well before the liquid became syrup-like, so I don't think that I can use that as my guide. The sudden foaming of tiny bubbles right at the end was my cue to take the pot off of the fire and pour it through the filter, and I think that it worked perfectly.

I have another 7 or 8 gallons of sap that I'll try to process tomorrow.

This stuff is fun, isn't it...
