Here are the two lots straight from the oven – I roasted them for another 5 hours this morning.
LHS is new tin, 9 tea bags, RHS old rusty tin, 6 tea bags.
Can you see the problem?
Maybe this will make it clear; below -LHS old rusty tin, RHS new tin.
LHS perfect, RHS not so perfect.
The key to getting the lovely metallic grey/brown is the old rusty tray.
I now have a very precious rusty roasting tray. Just what every girl needs.
