The other issue that I have come across, and the main problem that this Instructable addresses is that I can never even find the packets that I really want. Olive Oil, Chili Oil, TABASCO, Vinegar, and Maple Syrup are a few. The Other great part about this Instructable is that it is SUPER EASY. Anybody can do it! You don't need to sew, you don't need a to be a rocket scientist, you don't even really need any tools.
Step 1: [Buy Some MIO]
Step 2: [Remove Top Section and Rinse]
Now you can rinse out any leftover MIO. If you're as frugal as I am you could get a bulk of the MIO out with some water, and put it in a glass to drink. You may want to let the rinsed out bottle dry on a rack if you are going to be putting any oils in the container, since oil and water don't mix very well.
Step 3: [Fill and Recap]
Fill your container with the condiments of choice and label what you put in them. Three special notes follow:
1. Since the MIO is a concentrate, it may impart a fruity characteristic to your condiment of choice.
2. You may have noticed that the MIO spout has a no drip cap. Keep in mind that solids will clog this so any condiment with "bits" in it are not recommended.
3. Some condiments may require refrigeration. Please use common sense and keep this in mind. To keep neighboring condiments from spoiling you could fill a MIO container with plain water and freeze, then deploy these frozen MIO containers throughout your pack to keep temperatures from getting too warm.
4. I have successfully taken my chili oil and olive oil on camping trips in these containers and did not have any issues with seepage or leaking. If you are backpacking you may want to wrap it in a baggie or stow it inside your pot where it won't get any added pressure on the bottle which is of course how you remove contents from plastic bottles.
Step 4: [Fin]
Stay safe, have fun, and happy trails!
