Bought 2 fresh mackerel from fish counter on Sat. Got them to remove heads, but otherwise whole. Just put them under the grill, but one feels firm (as I'd expected) and other feels all floppy. Is this ok, or does this mean that the floppy one is bad? Both seem to smell ok I think.
Grilling now - so you only have a few mins to answer before I need to eat or bin!
Thanks!
