Why did my baked custard turn curdy?

[AnyDream]

That's what I thought, Trill (about the bain marie) but it wasn't in the instructions so I didn't do it. Should've trusted Nanna's way.

What temp would you do your baked custard at?

I do mine at 120 in a bain marie.

Other way to stop it curdling is to add the tiniest bit of flour (probably about 1tsp for that mixture) but that is only if you are going to have to cook it faster - the slow cook is always the best way.
