Last night I did the following:
- Threw 2 eggs & 1/3 cup sugar together
- added 1 mashed banana, 1 tsp vanilla, & 1 1/2 cup part skim (99%) milk
- mixed thoroughly
- poured in 4 custard cups
- put in 350 oven, in a baking pan with 1/2 inch water
Instead of taking the expected 30-40 minutes to cook, it was still liquid after 45 minutes. It didn't get solid until it had baked for 1 hour. By that time the water in the pan had evaporated.
The custard was curdled. What happened? I've done this I think basically the same way before without a problem.
