My mom was gifted a Dunn's smoked brisket, and I greatly look forward to it.

The donor told us to cut into smaller portions, Ziploc, and freeze. And to reheat by steaming or air frying. But we don't have an air fryer, or a super convenient way to steam things tbh.

Any alternatives or second opinions on how we should store and reheat these?

I imagine the reheating method matters more for eg a proper bbq brisket portion or a slice for a sandwich. And for things like chopping them up and putting into pasta or a taco, less so.

Any and all thoughts appreciated ???????? ty in advance
