Have you ever eaten something foreign for the first time and thought, “This could sure use some hot sauce”. Sometimes its not a matter of disliking the food, its just a desire to enhance flavor. Thank god for these travel-friendly sauces! So many variations. So many heat levels. If you find a favorite, you can order in bulk.
As for transportation and luggage leak-prevention, we all have a spare eyeglass case right? An empty prescription bottle? Small [disposable] tupperware? A child’s pencil box? I mean, if you do not have any of these items I know I’ve seen most at my local dollar store, so its probably the same case for you. There’s a [relatively] nearby dollar store, right? They’re everywhere and I live in the country.
