To keep ice for the plantation, Thomas Jefferson constructed an ice house. In the winter of 1802-1803 the summer's harvest of wheat was safely stored in barrels and barns. Monticello overseer Gabriel Lilly had to wait for freezing temperatures before he could harvest his next crop: ice from the Rivanna River.
"Ice-creams were produced"
Ice cream frequently appears in visitors' accounts of meals with Thomas Jefferson. One visitor commented: "Among other things, ice-creams were produced in the form of balls of the frozen material inclosed in covers of warm pastry, exhibiting a curious contrast, as if the ice had just been taken from the oven."
