Skordalia (garlic sauce)
For the cod
Remove the skin from cod and put the cod in the water for 24 to 36 hours while you occasionally change the water (3 to 4 times).
Prepare the batter in a large bowl by mixing the beer and flour until it becomes a dough that will stand nice on the fish and will not run.
Fry the battered cod in very hot canola oil and for a while, until it’s done. (Caution spits).
Put the potatoes to boil in plenty of salted water. Beat the garlic on a wooden mortar until it becomes a sleek paste.
Check how well - cooked the potatoes are by piercing them with a fork. Once the potatoes are cooked, take them out of the hot water, peel them and mush them in the mortar along with the garlic, throwing each time a spoon of oil and lemon. Do not add too much oil at the beginning because if you put more than needed, it will be difficult to make a smooth cream.
Continue to mush them in the mortar by gradually adding olive oil and lemon until they become a velvety paste and you satisfied with its taste.
Mushing with the mortar takes about an hour. If you want to shorten the time you can skip the last step by passing the garlic sauce in doses from the mixer or multi.
You can serve it with some parsley to give color and aroma to the plate.
