The refrigerator holds for another 4\u20136 hours. The freezer lasts 24\u201348 hours if it&#8217;s full and stays closed. After that: everything spoiled \u2014 unless you act.<\/p>\n\n\n<p>These 6 methods help you keep food fresh as long as possible without power.<\/p>\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n<h2 class=\"wp-block-heading\">Method 1: Canning<\/h2>\n\n\n<p>Canning is the oldest and most reliable method of food preservation. Fruit, vegetables, meat, and soups are sterilized in mason jars at high heat and then keep for years \u2014 without refrigeration, without power.<\/p>\n\n\n<p><strong>Shelf life:<\/strong> 1\u20135 years depending on contents.<br><strong>You need:<\/strong> Mason jars, a large pot, a camp stove.<\/p>\n\n\n<p>\ud83d\udc49 <a href=\"https:\/\/blackout-ready.de\/beste-gaskocher-blackout\/\"><mark style=\"background-color:rgba(0, 0, 0, 0);color:#0693e3\" class=\"has-inline-color\">Best Camp Stove for Canning Without Power \u2192<\/mark><\/a><\/p>\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n<h2 class=\"wp-block-heading\">Method 2: Freezing \u2014 But Prepared Correctly<\/h2>\n\n\n<p>During a blackout: <strong>do not open<\/strong> the freezer. It holds for 24\u201348 hours when full. Wrap blankets or sleeping bags around it for extra insulation. In winter: move food to the balcony or into your car (if cold enough).<\/p>\n\n\n<p><strong>Immediate tip:<\/strong> When the blackout starts, quickly use up the refrigerator contents (these spoil faster) and leave the freezer untouched.<\/p>\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n<h2 class=\"wp-block-heading\">Method 3: Dehydrating \/ Drying<\/h2>\n\n\n<p>Dried foods last months to years without refrigeration. Meat (jerky), fruit, vegetables, herbs \u2014 all of it can be dried.<\/p>\n\n\n<p>Without power: dry in direct sunlight in summer (on a clean cloth), or over a camp stove on low heat.<\/p>\n\n\n<p><strong>Shelf life:<\/strong> Dried fruit 6\u201312 months, jerky 1\u20132 months.<\/p>\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n<h2 class=\"wp-block-heading\">Method 4: Preserving in Salt or Vinegar<\/h2>\n\n\n<p>Salt and vinegar effectively inhibit bacterial growth. Cucumbers, onions, meat, fish \u2014 almost anything can be preserved this way.<\/p>\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Curing (salt):<\/strong> Pack meat and fish in salt \u2192 shelf life weeks to months<\/li>\n\n\n<li><strong>Pickling in vinegar:<\/strong> Vegetables in a vinegar brine \u2192 shelf life months<\/li>\n\n\n<li><strong>Oil preservation:<\/strong> Herbs, cheese, vegetables in olive oil \u2192 shelf life weeks<\/li>\n<\/ul>\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n<h2 class=\"wp-block-heading\">Method 5: Fermenting<\/h2>\n\n\n<p>Fermentation is easier than you might think: vegetables + salt + time = sauerkraut, kimchi, or pickles. Fermented foods are preserved by their acidity and are even more nutritious than fresh produce.<\/p>\n\n\n<p><strong>No power needed, no special equipment.<\/strong> Just salt, vegetables, a jar, and 3\u20137 days of waiting.<\/p>\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n<h2 class=\"wp-block-heading\">Method 6: Cooling Without Power<\/h2>\n\n\n<p>A &#8220;Zeer pot&#8221; (pot-in-pot cooler) cools through evaporation \u2014 no power needed. Two clay pots, sand between them, keep damp. The interior temperature stays significantly cooler than the outside temperature.<\/p>\n\n\n<p>In winter, a basement or north-facing balcony often serves as a natural refrigerator.<\/p>\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n<h2 class=\"wp-block-heading\">What to Do Immediately When the Power Goes Out<\/h2>\n\n\n<ol class=\"wp-block-list\">\n<li>Refrigerator: eat or cook the contents quickly<\/li>\n\n\n<li>Freezer: don&#8217;t open, insulate<\/li>\n\n\n<li>Sensitive foods: can or pickle immediately<\/li>\n\n\n<li>Prepare your stove \/ camp stove<\/li>\n<\/ol>\n\n\n<p>\ud83d\udc49 <a href=\"https:\/\/blackout-ready.de\/kochen-im-blackout\/\"><mark style=\"background-color:rgba(0, 0, 0, 0);color:#0693e3\" class=\"has-inline-color\">Cooking During a Blackout: How to Prepare Meals \u2192<\/mark><\/a><br>\ud83d\udc49 <a href=\"https:\/\/blackout-ready.de\/https-blackout-ready-de-herd-ohne-strom\/\"><mark style=\"background-color:rgba(0, 0, 0, 0);color:#0693e3\" class=\"has-inline-color\">Stove Without Power: All Options at a Glance \u2192<\/mark><\/a><\/p>\n\n\n<p>For complete blackout preparation:<br>\ud83d\udc49 <strong><a href=\"https:\/\/blackout-ready.de\/beste-notfallrucksaecke-blackout\/\"><mark style=\"background-color:rgba(0, 0, 0, 0);color:#0693e3\" class=\"has-inline-color\">Emergency Backpack with Cooking Equipment: The Best Models \u2192<\/mark><\/a><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>When the power goes out, the clock starts ticking.
