And also if I was allergic I would have had to try it to know that I was allergic unless I did some sort of allergy test at a clinic which I did not do. But yeah I'm not allergic and I have tried eggs and their yummy

u need like a square/rectangle pan to get the best shape
6 tamagos
shit ton of sugar maybe like 2 tbs? dunno
half a tsp of salt i guess

put small layer onto pan (with oil ofc) first
cook on very low heat
roll it up onto one side
chuck another layer on
cook and then roll up and repeat until all tamago finished
make sure not to overcook the tamago
