When I order take out, I ask for complimentary condiments to go with our meal. These condiments add up and sometimes I don't even have to buy these ingredients.
I just cleaned our kitchen table and found that we have 2 cups of butter and some parmesan cheese and crushed red peppers packets. I also have some ketchup in the fridge.
Not only are these little packages useful, but they can be convenient for picnics, packaging your child's lunch, or on the go - in addition to using at home for everyday cooking. Same applies to utensils.
I bought these metal tin containers for 90% at Target since they were a part of the Easter theme. They come in useful for organizing.
Save those packs of mayo, mustard, ketchup, relish, lemon juice, honey, etc. Put them in a bowl in the frig. When you need some for your lunch bag there you are. No mess or fuss.
Save all those extra condiments from fast-food meals. (My local McDonald's drive-thru always gives me a handful of ketchup when I ask for ketchup for one, so they really add up.) Then, use them for picnics in the summer.
Every time I eat out, I receive tons of extra condiment packets. Usually, I don't need them, but I hate wasting food. I originally stored them in a ziplock baggy, but decided to find a container instead.
At a restaurant supply store, I purchased a gallon of prepared yellow mustard for nearly $3.00. I bought it only for fill-ups for my regular sized squeeze mustard bottle, for everyday use.
