I'm too lazy to pull down my spicy food cookbook and look it up! It's for roasted veggies.
Depending on your experience with REH , you have a wide range of spices to choose and blend to make this mix. Most I have tasted have cinnamon,clove,pepper,cumin,allspice,ginger,coriander,celery seed,fennel,and many other unknown spices added whimsically to the mix. it is a firey blend that is rarely the same twice...good luck !!!
Here's one from Kitty Morse in The Scent of Orange Blossoms, a lovely book.
2 tsp gr allspice, 1 tsp gr nutmeg, 2 tsp gr mace, 1 tsp gr ginger, 1/4 tsp gr black pepper, 1/2 tsp salt, 1/2 tsp gr cinnamon. You can use toasted whole spices and grind them.
This should be wonderful on roasted veg. I'm thinking sweet potato....
