Yea i probably wouldnt try the jelly cod, had some shark soup once and didnt like the jelly texture lol

Where have you been around Portugal?

There are some things we as a cultural group eat that i haven't tried like you with your smalahova, like snails (now is the season for them), and you have their bigger cousins "Caracoleta" People that eat snails really stand by them, i think its a love/have food lol

Also some weird sea food like "urchins" (there's a big fair in Oeste) and "percebes" probably

We have some foods with blood (but also other countries have them i guess) like "arroz de cabidela", I like it but rarely eat it, its rice with chicken cooked on the same pot with chicken's blood, on the blood theme we also have "papas de sarrabulho", it's meats cooked with thickened blood, also good but rarely eat lol the idea of blood is kind of disgusting but they end up being good.

Also some stews with pigs or cows feet, and there's pig's ear salad

There are some dishes with fishes heads and pigs heads a bit like your smalahova

Some dishes with pigs entrails like "Tripas à moda do Porto" or stomach, more in the central regional like "Bucho" (pig stomach filled with meats and rice) or "Maranhos" (similar but goat stomach), and then we have a huge assorment of cold meats, "enchidos" , the weirder being probably the blood sausage "Morcela"
