My family really enjoys make maple syrup right from the trees in the back yard. We only make a little each year and so do not have any specialized equipment. This year I employed an expedited version of a rocket stove made from cement blocks to boil the sap. It was quite efficient. We did not use much wood and produced something close to a quart of finished syrup.
Nothing I have ever purchased has tasted as good or been as satisfying as what we make in the back yard.
Are this blocks simple cement or refractory? Delicious this maple syrup :)!
They are just regular cement. Something else would be better and more expensive.
Thank you!
