I would love to make some beef stock with bones, but I have no oven in which to roast them! I have a small roaster oven that doesn't brown well. I was wondering if browning the bones in a pan with a little oil would be a suitable substitute for roasting? Is there something very specific and necessary that roasting in particular does that cannot be achieved on the stove top? I think it would just impart maybe a different flavour. Anybody tried this?
