I came across the idea of boiling apple cider into syrup and had to try it. I boiled 2 1/4 gallons syrup for about 3 hours into 3 pints of heavenly syrup. I added a few mulling spices as well and strained the hot syrup directly into canning jars. So wonderful and very easy. Don’t let cider season go by without trying this. No recipe. Just boil until you get a syrup you are happy with. Watch closely near the end. My own experiences in maple syrup production taught me how quickly syrup can become burnt, smelly, sugar that cannot be removed with all the elbow grease in the world.
