When to harvest
It is true that oyster taste best in months with a "r" in it. That's because in the warmer months they are spawning, which makes them milky, soft, and not as flavorful. Also, as filter feeders there is more algae & human produced pollution in the water which alters the taste. In the colder months they firm back up and retain less fluid so IMO are much better. Besides, let them drop their spat for another harvest in a couple of years.
