Semi-frozen brisket cook advice needed

gmac

I pulled a 4.8 kg (10-12 lb?) brisket out of the freezer yesterday and put it in the cooler to thaw. But it's still very hard today. I am gonna leave it out in water to thaw more but it may still be somewhat frozen.

Any issues putting it on for an overnight at 225-250?  Want to do burnt ends so want it done in decent time. Figured slow overnight and then can wrap and turbo if needed tomorrow. 

Option 2 is to see how much it thaws today and put it on about 2 am or so as I have to pick my son up from work after his shift 
Thanks

If you change out the water every 45 minutes or so you will get it fully thawed by early evening.  Then go will whatever supports your schedule.

no issues putting it on partially frozen.  will add a little to cook time.

Agree with @lousubcap but worst case throw it on little frozen. Good luck.

Agree with all above. Mine thaw out in a few hours in water. I think you should be ok.

It's pretty well thawed now so I will just treat it as normal but thank you all for the input.
