I just found these resealable, airtight, food grade spice bags (online, Amazon). Obviously, you can seal them if needed, but I do not. I wanted something to easily pack seasonings for traveling.
They are perfect for taking seasonings, and homemade mixed grill seasonings, for camping or traveling. These packets are much sturdier than using snack size ziploc bags or snack bags.
If you are renting accomodations, that provide a working kitchen, or grill, these are great for packing spices, seasonings etc. We once rented accomodations, and took seasoning already mixed up for a specific baked chicken recipe.
These are great to take to picnics, or if you are the grill cook at another get together too.
Often times, eating a burger at a restaurant can be under seasoned or not seasoned at all. We've decided these packets were perfect for taking some homemade Montreal Steak Seasoning in, while dining out for a burger.
If you are taking more than a few for camping, hang a piece of string and use clothespins to hold each packet in the kitchen area of the camper. Just an idea for campers. Of course there are magnetic spice bags and containers too, but our camper lacks the areas for magnetic anything (including the fridge).
Note: We do not keep any food of any kind inside the camper, unless we are actually camping.
