My whole life I've been buying small squid (maybe 4-6" long bodies without the head and tentacles), which are very mildly chewy and tender. All it takes is sautee them in a little OO and they are good to eat, IOW, no additional tenderizing is needed.
Yesterday I got some large squid, about 1 lb each before cleaning, probably 10"+ long without the head, probably 5-6 times as much meat as the little ones I usually get. I remember trying to cook that before and they came out very tough and with a bit of unpleasant odor.
Is there a way to marinate and tenderize large squid and to somehow neutralize the odor?
