Arm blade roast - cooking ideas

[Owlie]

I've a grass-fed arm roast that is much too long to fit in my crock pot - so it will have to go in the oven. I've a glass dish it will fit in and aluminum foil will seal it nicely. I've not much experience with cooking red meat - many of the recipes I've seen appear to assume that this type of roast requires marinating for a couple of days Is that really necessary? I know that it needs slower cooking, pity it won't fit in my crock pot. Right now I can't do anything with it until it thaws - the meat I get from my grass-fed farmer are frozen HARD - it takes longer to thaw then frozen meat from the store for some reason.

You might have to marinate it. Those sorts of meats can be tough even with slow roasting. Is it bone-in? If not, you might be able to cut it to fit in the crockpot.
