You guys, you HAVE to try this recipe for maple chipotle flank steak tacos! Today a few friends and I are talking all about pure maple syrup recipe. Plus what actually happens inside the sugar maple trees to make the sap run.

Maple Chipotle Flank Steak Tacos

I don’t want to sound like a broken record, but this spring is really starting to annoy me. And that’s putting it nicely. We normally would be waist deep in sap by this time in March. You can read about our backyard maple sugaring adventures here and what I like to cook for the friends who come to help here.

But instead we have had record breaking cold temps and our trees haven’t been able to do their thing here. (See more about how they do their thing in the blue box below.) There has been some sugaring here in Vermont, but we live in the foothills of the Green Mountains, at about 1,000 ft. altitude, so it is just cold enough here that we haven’t had a run yet.

What Causes Sap To Flow In Maple Trees

Here’s what actually happens inside the sugar maple trees to make the sap run, and why the conditions have to be just so for a run to happen. It starts off when the temps start to dip down for the winter. That’s when the sugar maples flush the water content out of its tiny twigs and branches to protect them from freezing solid and therefore be at risk for damage in the bitter cold temps. The tree produces sucrose to replace it. The sucrose won’t freeze, so the maple tree is protected.

Then in the spring when the days get up above freezing, but it is still cold at night, the ground starts to thaw and the tree will take up water from its roots again to flush out the sucrose. We tap into that flow and draw off the sucrose water. It’s really dilute compared to maple syrup. It actually takes about 40 or 50 gallons of sap to boil down to one gallon of syrup, depending on the sugar content of the sap itself. 

Our backyard maple sugaring operation in action mini evaporatorThe worst part is that, this year we upgraded our system, note I’m use the word “system” lightly, see above^^^, to double the number of taps and we even got a mini evaporator from Craig’s List.

So my husband is all excited about the new rig and he hasn’t even gotten a chance to use it yet. He is beyond excited that it is supposed to be warm enough today for a run so he’s taking the afternoon off so he can get going! Fingers crossed that it will run.
