I too liked Jeff's recipes. I personally think the cost it worth it. After all, he is hosting a website with over 1 million posts. I will say this, I thought Aldi's ketchup works better than Heinz. Just my 2 cents worth.
Same way with MSG, Dave - it's in a lot of store-bought rubs, too. I have to watch for that one; triggers migraines in the wife!
How spicy is Jeff's rub? My little one doesn't like spice so I'm searching for options that provide flavor without too much spice. OTOH, if I make it spicy that means more for me ha.
