I made the Nut Roast for the first time tonight. It turned out beautifully!
My tips would be:
* Tear the bread into really small pieces before you put it in
* I used about half the amount of milk called for, otherwise it would just be way too moist
* I scooped the mix out at the end and stirred it in a mixing bowl with a wooden spoon - the TM bowl was just too full and shredding everything on the bottom but not the bread on top
* It looks like it isn't cooked properly, but it is. It was hot in the inside and crispy on top, which was good enough for me. Its not like a meat loaf where the texture changes as it cooks.
* Its important to let it sit for a while before serving, and even after I'd sliced it and plated up, I noticed the middles was still thickening a bit as it cooled.
Hope that helps!
