That is how she began her specialization process as main singer in the santería religious ceremonies. About her relationship with Ortiz, Merceditas said: "One of the most beautiful and enriching experiences in my life took place when I became the only singer performing for Don Fernando for his lectures. With the passing of time and the deepening of our friendship, he nicknamed me "his small Aché", because he used to say I brought him good luck."
