For all of these rubs except the all-purpose one, you?re going to need a spice grinder to really get the full flavor of the rub. Sure, you can find ground versions of all of the ingredients, but it?s so much better to use whole spices. They are more flavorful, the whole spices keep longer, and they are generally cheaper. The Coffee Rub For this rub I wanted a dark mix that would hold up well on flavorful meats. You wouldn?t want to use this guy on light stuff like fish or chicken. Start with whole beans, a small piece of cinnamon and some cardamon seeds. You can use pods also, but I like the seeds. Coffee stuff Any coffee will do. Grind up these spices and then add in all your other spices to the mix. This rub has the most ingredients in it and the resulting flavors are pretty complicated. It?s a very good rub though. coffee rub Lots going on here. Once I had my rub mixed up, I coated a thick pork chop with it for testing and grilled it up. The results were amazing: coffee pork chop No big deal. The 5 C?s Rub For some reason a lot of spices start with the letter C. Or maybe just my favorite spices start with the letter C? In any event, I thought I?d mix them all up and see what happened. five The Five C's of delicious. For this rub, I lightly toasted my cumin, cardamon, and coriander in a dry skillet for a few minutes until they were fragrant. Then I just blended them up! 5 c mixed I think this might also be good on popcorn. The 5 C?s Rub is the lightest of the rubs I made for this post. It has an almost sweet flavor to it that would go well on chicken, tofu, veggies, or maybe even a sturdy fish. All Purpose Rub While I was mixing up rubs, I thought I?d give you all the recipe for my favorite all-purpose rub. I use this stuff on everything. It?s great on steaks, chicken wings, asparagus, roasted tofu? you name it. There?s also no grinding involved. Just take all the spices and stir them up. It takes maybe three minutes to mix up a batch! All purpose Good on shoes! Grilling Some Chicken To test out the all purpose rub and the 5 C?s rub, I generously coated a few chicken breasts with both and grilled them. The breasts on the left are the all purpose rub and the right breasts are the 5 C?s version. bam Really good chicken. I loved all of these, but I really liked the 5 C?s rub. It gave the chicken a really bright flavor that was very unique. These rubs will all keep for a month or two without losing much flavor. I keep mine in plastic bags, but if you had a few airtight containers, they would keep even better. Not that there?s any chance mine will last that long?
