Which has nothing to do with being gf but is a good read none the less.
So my experimental dinner was a beef roast, where I used a marinade as a dry rub. I used a citrus marinade I think it would have been better if I used a peppercorn rub instead. It still tasted good and was really moist since I used the crockpot and put a little bit of water in it.
