Food would be smoked, dried, salted, fermented or pickled. It would also be kept in root cellars or pits underground. Wealthy people who lived in cold climates were more likely to have an ice pit or later an ice house where they would keep ice for use in warm months.
How long will milk/eggs last during a power outage? Milk, eggs, fish, meat and leftovers will last four hours in the refrigerator, as long as the door stays closed the entire time.

Colonists preserved food using eight basic methods: fermentation, burial, drying, curing, cooling, freezing, pickling, and canning. Fermentation happens when starches and sugars react with microorganisms and produce alcohol.
Drying is the oldest method of food preservation. This method reduces water activity which prevents bacterial growth. Sun and wind are both used for drying.
Buy dry or block ice to keep the refrigerator as cold as possible if the power is going to be out for a prolonged period of time. Fifty pounds of dry ice should keep an 18 cubic foot, fully stocked freezer cold for two days.

Dehydrating is a traditional Amish technique that uses only sunlight and airflow. Foods like apples, herbs, and tomatoes are laid out on racks in the sun, allowing moisture to evaporate slowly. By removing water content, dehydration keeps foods shelf-stable for months, all without the need for an oven or dehydrator.
to keep food cold in the refrigerator if the power might be out for a long time. After 4 hours without power, put refrigerated perishable foods in a cooler. Add ice or another cold source to keep them at 40°F or below. After Never taste food to determine if it is safe to eat.

Wood to heat the house and fuel the kitchen stove had to be cut and split by hand. Water was pumped from a well and had to be hauled, bucket by bucket, to the house or barn. Cows were milked by hand. The “toilet” was an outhouse in the yard.
Native Americans developed ingenious food preservation techniques to ensure year-round sustenance. From sun-drying berries to smoking fish, these methods not only extended shelf life but also enhanced flavors and nutritional value.
Vegetables were often salted or pickled. Many fruits were dried or turned in preserves. These foods could then be stored in cool places, like cellars and caves. This allowed people to save food for times of need during droughts and famines.
Refrigeration without electricity
If ice or snow wasn't an option, underwater or underground storage, like cold cellars, provided refrigeration. People also began building their own iceboxes for cold storage, using chunks of ice or snow in boxes insulated with natural materials like sawdust or seaweed.
