I ordered a sample from this company and tried it this weekend. The sample request got me one pouch of Fettucini Alfredo. The food is freeze dried and very light and packed in a fairly heavy foil pouch. Instructions are easy and printed on each foil pouch. I didn’t measure the dry volume but would estimate about 2 cups in a heavy foil pouch that would fit in a cargo pants pocket. Instructions say to bring 4 cups of water to a boil, stir in contents of the envelope, cover and wait 10 minutes. The result is 4 servings and was pretty good. It wasn’t Fettucini Alfredo that was prepared with fresh cream and butter but was good. My guess is that in an emergency when you may not have eaten for 18 hours it would be great. You can order your own sample on the website. I’m trying to get a few dozen samples to give away on meeting night. These folks package their freeze dried foods in heavy foil pouches and package the pouches in plastic buckets that are about 1/2 the size of a 5 gallon plastic bucket. SHELF LIFE OF THIS FOOD IS UP TO 25 YEARS WITH PROPER ROOM TEMPERATURE STORAGE. This allows you to grab them and go for camping or a bugout to a safer location. I have 2 of their 84 serving buckets stashed for an emergency. 168 servings may sound like lot but it amounts to 2 weeks for 3 people with 3 meals and one snack per day. If you are just sitting in a shelter that may be fine but you might need to allow for more calories if travelling on foot or doing hurricane cleanup/repairs at home. DON’T FORGET YOUR PETS. Our dogs are valued members of our family and even a small dog can alert you to a prowler outside. Buy ahead for your pet and rotate the stock. Also talk to your doctor about your medication needs during an emergency when you may want to shelter in place in your home. Some of us are used to buying daily at the grocery store. Think ahead, buy ahead just in case. There are plenty of reasons to stay off the streets for a week or two, local hurricane/tornado damage with roving gangs of looters, a disease pandemic, rioting due to an unpopular election or court decision, economic uncertanty etc. Think about having food/water/medication to wait out the emergency. You can also check your local supermarket and buy normal supermarket food for emergency storage. Look at best by and expiration dates, buy the food you normally eat and rotate your stock.
