I came across the spice Tajín Clasico and it was an instant match for my recipes and cooking. 

Tajín is ground mild chili peppers, lime and salt. There are no artificial ingredients, colors or preservatives. A perfect combination of ingredients. 

The chili factor is mild and not too spicy. The lime factor is perfect for marinades. I marinade my chicken in the Tajín spice with a bit of olive oil overnight. 

What I get is a flavorful marinate where the mild chili gives the chicken a great flavor while the lime complements the chicken and makes it succulent and ready great for grilling.
