Fa'amatalaga: 1. E tatau ona fa'avevela le eletise i le vevela o le 350°C mo le 1 itula. Fa'avevela muamua le u'amea pe a fa'aaogaina.
2. E tatau ona faʻamamā ese mea leaga e pei o le ele, pisipisia o le suāuu ma le susu mai le fasi galuega.
3. E manaʻomia se au pupuu e faatino ai le uelo. E sili atu le auala vaapiapi o le uelo.
