I haven't bought 'rubs' in decades.
They are high in sodium, some even MSG, and most are not made with organic ingredients.
All of them are over-priced, way over-priced for what you get.
I love hot-spicy, but I love flavor, chile pepper flavor, even more, and you can't regulate
that with store-bought rubs. There are some that taste good, but all of the above still
goes for 99% of them.
Anyone can grow chile peppers, almost anywhere you live, and you can easily grow a bunch.
Growing and dehydrating your own gives you incredible versatility for uses........
Grow a variety, prepare them, then mix them how you wish.
Then you can add Himalayan Pink salt, organic peppercorn [black, white, rainbow],
granulated garlic and/or onion, ginger, turmeric,rosemary, cilantro, etc,or whatever else you want.
I use a large variety of peppers each day, and it's not always for HOT meals.
They are very healthy for you.
