LOL Make just a small batch til you know which ones you like or need to adjust. When I do the taco one I make like 4 batches at once as I really like it and use it a lot. Or just gather all the spices you need and sit down and make a batch of each and put into sandwich bags, label and then you can leave comments on your bags so you know which one you prefer.
I will do that! I will probably wait to try some of them since I still have a lot of some commercially produced low salt spice blends in my spice cupboard. I cook a lot for a family of 5, so I tend to buy them in larger containers or in bulk. I think I still have about a cup of Cajun Seasoning left and 2-4 cups left of Fajita and Taco Seasoning at the moment, but I go through them all fairly fast, expecially with the nice weather coming soon when we will be cooking more on the BBQ.
