I’ve been doing this for years does to having a compromised immune system. When I had kids I got sick a lot and I needed food in to feed them. So I’ve always had a stash to make sure they could eat while I was trying to survive the recurrent MRSA/ pneumonia I was plagued with. Its smaller these days as they have mostly left home but in the food supplies i have around 18 tins of chunky veg/tom/chicken soup. 8 tins beans and sausages, 4 corned beef, 2 bacon grill, 4 tubs dried mash, 6 spaghetti boll, 4 mushy peas, gravy, curry sauce, 4kg pasta, 6 passata, 6 meatballs, 6 tinned peas/carrots, 4 tinned peaches, 4 tinned fruit, 4 tinned grapefruit, 6 rice pudding. Various cordials, coffee, tea, milk powder. Then a load of various noodles,flour, sugar, stock cubes, rice, lentils, split peas, curry powder, herbs, spices and cooking oil. 25 litres of water not I also have a RO system so water isn’t a concern as long as I can remineralise it.
we are avid campers so we have rechargeable lanterns, gas stove and canisters, candles, power banks. Hoping to get a 1000w power station and solar panel on the Black Friday sale.
i also bulk buy shampoo/soap/loo roll/laundry/toothpaste. So i could very easily not leave my house for 3 weeks minimum, especially with me having a chest freezer full of meat. I recon I could go for 5-6 weeks before things started getting sketchy and meals would be random mish mashes.
