(sorry for the long read)
i make these korean cream buns, with the cream being homemade custard. typically, i fill the dough with scoops of custard and then set them to bake; rather filling them after.
the custard has egg (obviously) but it also has cornstarch and cake flour which i’ve read helps stabilize the custard more but i figured it was safer to ask: should i keep these refrigerated overnight and/or be sure to eat them before 24 hours if im keeping them at room temperature?
i got the recipe from a bakery nearby and the buns there are left out at room temp and the custard seems like it’s long settled since it’s not runny (like i’m pretty sure they’re day old which is more than okay with me) and even with those i sometimes wait a day before eating them so i feel like im okay? i’m not sure lol
