Answer: not very, although be prepared to make a bit of a mess.
I used petrale sole for this dish, which is rated a "good alternative" by Monterey Bay Seafood Watch. (Definitely check your potential fish for sustainability before buying!) Any whitefish will do; I prefer flatfish (especially flounder), but cod seems to be the standard.
Fish and Chips for two
First, prepare the french fries or "chips." Preheat the oven to 400°F. Cover a medium baking sheet with aluminum foil and spray or brush with a light coat of olive oil. Cut 1 russet potato into the requisite shapes, first by cutting in half lengthwise, then each half into slices about ¼ inch thick, then each slice into strips from ¼ to ½ inch thick. Place the strips in a bowl of cold water and swish around (to rinse off some of the starch), then dry them on a towel. Distribute the strips onto the foil-covered tray, spray/coat with a little more olive oil, and bake for about 20 minutes, turning at least once.
Be sure to season the french fries as soon as they come out of the oven, with salt and pepper (and garlic powder) to taste. Serve your fish and chips with the classic condiments: malt vinegar, tartar sauce (relish mixed with mayonnaise), and a fine English ale.
