Maple syrup boils at 7.1 degrees Fahrenheit above the boiling temperature of water, so a good thermometer can be used to determine when it's syrup and and the density can be measured. Â°Bx Degrees Brix (symbol Â°Bx) is the sugar content of an aqueous solution.
11. Pour the sap collected from the maple trees into the metal can. Be sure the sap drains from the can into the roasting pan below. 12. Heat the sap to evaporate its water. Add more sap to the warming pan, as needed. 13. Frequently check the temperature of the sap with a candy thermometer. When it reaches 219 degrees F, it converts to maple syrup.
