In a previous post, I shared a recipe I have for making your own taco seasoning mix. I also have a recipe that I use now and then when I make sloppy joe's. It is also from my "Make-A-Mix Cookery" cookbook. Just like the taco seasoning mix, this mix can also be made up ahead of time and stored in small foil packets in your freezer. Even though it only takes a couple of minutes to mix it up when needed, it is also handy to have them pre-made and ready at a moment's notice.
Sloppy Joe Seasoning Mix
1 tablespoon instant minced onion
1 teaspoon green pepper flakes
1 teaspoon salt
1 teaspoon cornstarch
1/2 teaspoon instant minced garlic
1/4 teaspoon dry mustard
1/4 teaspoon celery seed
1/4 teaspoon chili powder
Combine all ingredients in a small bowl until evenly distributed. Spoon mixture onto a 6-inch square of aluminum foil and fold to make airtight. Label. Store in a cool, dry place. Use within 6 months.
