@kstrantz We can do custom seasoning through Excalibur. They usually require large amounts being purchased at a time but if you had a specific seasoning you wanted to make without the bite that might be a good way to go? We would be able to tell them you like the taste of seasoning A but don’t like the spiciness and they could work to make a custom batch (available only to you) with a reduced amount of pepper? The only downside to that is the minumim amounts per order are pretty large.
If you are interested in that you could contact Walton’s Customer Support at 800-835-2832 or cs@waltonsinc.com
What @Joe-Hell says is probably the simplest way to go about it, the downside being that the other flavors might diminish as well. You could combat that by adding more of what you do like but even after all the test batches it might take to dial that in, it leaves a lot of room for error.
