Wash the outside of the oysters and scrub sand and algae off if necessary.
Take an oyster shucker in one hand and wrap a folded kitchen cloth around the other to give your hand some protection.
Place the oyster on another cloth on a cutting board flat side up, with the hinge (or pointy end) facing your hand holding the shucker.
Find the join between the two halves by wiggling the tip of the shucker until it neatly finds a little pocket just to one side of the hinge.
Push the blade in between the two halves until the tip of the blade is inside and gently twist to lever open the shell.
Run the shucker under the inside of the top half to release the little muscle (adductor).
Remove and discard the top half of the shell.
Clean out any small pieces of shell but do not rinse.
Cut the adductor where it is attached to the other half of the shell.
Dress your oysters with these and enjoy.
