Add: 70 days frozen test of mooncakes.
1). Picture of three testing mooncakes upon taking out of freezer - they look still good except their colors are significantly lighter than the freshly made ones.
2). Took one of the three,
sunshinecanada(Sunshine Canada)
and reheated it in a oven. The color is very good now after reheating step ( see the picture of single mooncake).
