You might use just a few tablespoons of maple syrup on your pancakes -- but it took about a gallon of maple tree sap to make that! This month the maple tree farms collect maple sap from their trees. They drill holes in the bark and stick in a "tap," or tube, so the sap can drip out into buckets. Then the farm folks cook the sap: They have to boil down 30 to 50 gallons of sap to make just 1 gallon of nice thick syrup. Much easier to keep a bottle in the fridge!
