Here is a story on a NJ spot
FRELINGHUYSEN — White clouds billow out of the top of the building. But it's not smoke, and when you walk through the plank door with the wooden slide latch, you can see the steam-producing mechanism.
The combination of stainless steel pans is almost obscured by the gallons of water vapor rolling off the surface in copious amounts that spread out around the sides of the metal hood meant to collect them but fail miserably in the effort.
Over, under and through the clouds of steam is a sonorous roar of the blower for the oil-fired flames, visible through tiny seams where the steel parts of the evaporator pans come together.
As you step closer, you cross the smell boundary and your senses tingle with the expectation of a stack of flapjacks with fresh butter and hot maple syrup running in rivulets down the side.
This mid-morning Sunday at Sarah's Syrup on Kerr Road, just off Route 94, Gary Kapitko was boiling down maple sap — a clear, water-like liquid — to produce the much sought-after pale amber of Grade A maple syrup.
Talking to Kapitko, it is clear this process is more than just a business that started as a driveway project with his daughter, Sarah, when she came home excited about a school lesson on how maple syrup is made.
