SHAD ROASTED ON A BOARD.
21. Take a piece of clean oak board about three inches thick, and two feet square, stand it before the fire till the board is very hot, indeed almost charred. Have your shad split down the back, cleaned, washed, wiped dry, and seasoned with salt; fasten it to the hot board with a few small nails; the skin side should be next the board, place the board before the fire with the head part down; as soon as the juices begin to run, turn it with the tail down; it should be turned frequently in order to retain the juices. When done butter it and serve it hot. Send it to the table on the board.
This is the receipt for baking shad at the Philadelphia "fish house."
