Here in Japan, and shizuoka in particular we have an abundance of squids (cuttlefish) and we do need to sometimes rack our brains for new recipes.
I understand that such sea food is not all that popular in some countries (in Muslim societies they are prohibited) but they make for tasty and reasonably cheap food.
Here is a (actually three ) simple recipe to enjoy them with a great glass of beer!

INGREDIENTS:

-Deep-fried suid:
Whole cuttlefish for three recipes at the same time
Flour
Egg
Panko/Breadcrumbs
Oil

-Deep-fried squid rings:
same squid
Flour
Water
Salt
Black pepper
Curry powder
Oil

-Deep-fried squid tentacles:
Same squid
Salt
Black pepper
Cornstarch
Oil

RECIPE(S):

Even if you mean to eat it only cooked choose a squid of the best freshness for best taste!
My favorite is Yari Ika/槍烏賊/Spear Squid
First pull out tentacles and keep them separately.

Take and throw away entrails That is unless you want to use the squid ink!).
Clean the whole inside and outside a first time with cold clean water.
Peel of whole outside skin. For better explanations and understanding look at these pictures describing the preparation a squid in detail!
Clean again and sponge off any excess water with a clean kitchen paper or towel.

Cut the body in rings. Leave the tail as it is or cut it in strings. Separate the tentacles or keep them whole.

Beat some eggs in a bowl.
Apply flour on all the squid cuts.
Dip into beaten eggs.

Bring oil to 180 degrees Celsius.
Deep-fry until nice orange-brown color.
Eat them hot dipped into a mixture of Worcester Sauce and tomato ketchup (or any suce of your liking!)

For deep-fried squid rings prepare a batter with water, flour, salt, pepper and curry powder (no need of eggs).
Dip the rings in the batter and deep-fry at 180 degrees Celsius.

Savor them crisp with a great craft beer!

As for the tentacles or geso/足 in Japanese, separate them to your liking and clean them in cold water. Sponge off all water.

Coat them with a mixture of cornstarch, salt and black pepper.

Deep-fry them in oil at 180 degrees Celsius just long enough to cook them. Soak off excess oil on a piece of kitchen paper or on a grill.

Serve them as hot as possible as they are or seasoned with chili pepper or/with mayonnaise!
Don’t forget the beer!
