I was going to make some steaks when I got home, should I not waste the rub. I could always put them in the fridge for a few hours.
I'd go ahead and do it - a few hours will be fine. They'll still be great.:tu
By the way, unless you like your steaks rare, don't make the fire too hot. Even with the oil, the spices will burn on a really hot fire. If you do like rare steaks it doesn't matter because they won't be on the fire that long anyway.
Rub, marinate for a bit and then cook.
BTW, you want steak? I'll send you a different rub. That one is specialized for pork. I've not tried it on steak. Let me know how that one turns out.
By the way how was that rub I sent you? I would be careful on how much you put on, many rubs can be salty. And if it is a good steak you do not want to overpower the flavor. To me the best marinating type steak would be a thick top sirloin marinated for at least a couple hours. This type of steak can be found on sale often and can be very tender and juicy if done right.
