What types of potato dishes freeze well? Which do not and why?
Jacqueline Thomas, New York, NY
Given the nature of the starch in potatoes and the relatively high temperature of home freezers (compared with the super-cold equipment used by producers of frozen foods), potato dishes don’t freeze well. The large ice crystals that form when you freeze potatoes at home change the texture, and most dishes will be watery when thawed.
There are a few potato dishes, however, that could be frozen, including twice-baked potatoes, which have a higher fat content due to added butter. You can also freeze mashed potatoes and reheat them in the oven or in a double boiler, but they won’t be the light, fluffy mash you started out with.
