Having never observed what I've ate. Excellent conclusion you've come up. Better luck next time!
By observational evidence.
Loooooool! Is that so!? And how did you come up to that conclusion exactly?
I suspect your culinary tastes are limited.
NZ has amazing huge mussels that I’ve never seen in Europe. Tasty and meaty. If they’re frozen then they’ll most likely have come here on a ship over several months. Better than flying fresh vegetables from Africa.
