We made our very own Maple syrup this year from 2 Sugar Maple trees in our yard. We tapped the trees in the 1st week of April and had about 10 gallons of Maple sap that we boiled down to 1/2 litre of Golden Maple Syrup. This video shows us boiling the sap down in our cast iron pot over a Bon fire in the back yard.... yum .
