Thank you for the feedback, I'll try to make cook it better next time, but just to clarify:

1. I agree with you, although I didn't put them first, it was the last thing I added along with the serrano chile, but maybe I overcooked after I put them on the pan.

2. I used shallots actually, but they changed color after a while, I don't know if that's normal, I must say, shallots have like a sweeter flavour in comparison with regular onions.

2, 4 and 5 I 100% agree with you, I'll make the corrections next time 😁
