Maple syrup is a syrup made from the sap of maple trees. In cold
climates, these trees store starch in their trunks and roots before
winter; the starch is then converted to sugar that rises in the sap in
late winter and early spring. Maple trees are tapped by drilling holes
into their trunks and collecting the sap, which is processed by
heating to evaporate much of the water, leaving the concentrated
syrup.
