Dannylang , hello . Get yourself some of all the Spices you like . Try experimenting with them until you get your flavor . . .get real Chiles like Ancho , N.Mex. , Pasilla , Pequeno , Smoked Paprika and so on ...
And get all the dried - whole Spices you can . They last longer if you but in quantity ...grind them in a Coffee grinder .
Later , Tater . . .
