As you probably know, maple sap is mostly water. So to get syrup, you boil off all that water. In the meantime, all that heat from boiling and all that water make the home a moist warm environment.
We enjoy it, and as the sap concentrates, there is a faint odor of maple syrup in the air. The photo shows how our kitchen windows steam up during the process.
You do not want to make maple syrup in a kitchen that is wallpapered. I’ve heard of people whose wallpaper neatly unpasted itself and fell to the floor in rolls.
Sapping and boiling are activities that indicate the change of season. When the sap runs, you boil. It’s a pleasant enough exercise but be warned that hauling buckets of sap in the snow can be awkward. When the sap runs, you boil, which can mean late nights as you finish a batch.
But the results are sweet.
