After skinning, cleaning, and washing them, cut them into short pieces, and dry them well with a soft cloth. Season them with salt and pepper, flour them thickly, and fry them in boiling fat; when nicely browned, drain and dry them, and send to the table with plain melted butter or butter substitute and a lemon, or with fish sauce. Eels are sometimes dipped into batter and then fried, or into egg and dried bread crumbs.
Follow same directions as for fried Cod.
Let the slices lie in cold salted water, to which has been added one cup of vinegar, for ten or fifteen minutes. Dry them afterwards thoroughly by wiping with a towel, and dusting cracker meal on both sides. Lay them in smoking hot fat, and they will be well cooked and of a pale brown in three or five minutes, according to thickness of the slices.

The best way to cook Smelts is to fry them, although they are sometimes baked. Open them at the gills. Draw each Smelt separately between your finger and thumb, beginning at the tail; this will press the insides out. (Some persons never take out the insides, but it should be done as much as in any other fish.) Wash them clean, and let them drain in a colander; then salt and roll in a mixture half flour and half corn-el. Have about two inches deep of hot fat in the frying-pan (drippings if you have them); into this drop the Smelts, and fry brown. Do not put so many in that they will be crowded; if you do, they will not be crisp and brown.
