Rinse the palm hearts and cut them into 1-2cm rounds. Then carefully push out the middles. You'll be left with rounds that look very similar to calamari rings. Set aside.
In a bowl mix the flour, garlic powder, adobo, and a pinch of salt. Set aside.
In another bowl, mix the cornstarch, water, and nori flakes. Set aside. Cornstarch may settle to the bottom after some time, Just mix to avoid this.
Heat the oil in the frying pan to medium-high heat. Test the oil by sprinkling some flour into the oil to check if it's ready.
Add the "calamari rings" to the cornstarch mixture, then to the flour mixture. Then add to the frying pan. Check notes.
Fry until crispy. About 1-2 minutes per side. Remove from the oil and place on a napkin to remove any excess oil.
Sprinkle with nori flakes and a pinch of salt. Serve with tartar sauce...AND DONE!!!
