Scrabble and King of Puddings

Brittany and I played scrabble while a pudding was baking for supper.........
I was winning!
Tried Jamie Oliver's King of Pudding recipe from his Happy Days with the Naked Chef.
This recipe has raspberry jam in it, which we all love , it has meringue which we all love , it is a custard, which we all love so what could go wrong?
Here it is going in the oven;where it is to bake for 1 hour or until set.
Here it is coming out of oven after the meringue has baked;

Yuck!
Did it taste good , yes, tho the girls did not go back for seconds.
"It was watery," said Brianne, and Brittany said,"unattractive looking"...took over 2 hours to cook til set.The meringue flattened.
What did I do wrong?
Here is the recipe;
4 eggs
2 1/2 cups milk
1/2 cup fine bread crumbs
3/4 cup and 2 TBSP. white sugar
4 TBSP. raspberry jam
Oven set at 300. Separate 3 eggs, Put the yolks and the remaining whole egg in bowl , beat together. Add milk, bread crumbs and 1/4 cup sugar.Put jam in bottom of a pie dish, spread evenly. Pour custardy egg mixture over jam. Bake for 1 hour til set.Whisk remaining 3 egg whites til stiff, slowly add remaining sugar, pile on top of custard and bake an additional 15-20 minutes until lightly browned.
The only changes I made which might have made this a failure was adding 1/2 cup frozen raspberries to custard ... cooked it in wrong size pan, used 2% milk not whole.
Has anyone else tried this recipe and succeeded?
