Liver Rolls
Ingredients
Directions
Cut the bacon into thin slices.
Scald the liver with boiling water, then cut it into pieces 2 inches wide and 3 inches long.
Season the liver pieces with salt and pepper, place a slice of bacon on each, roll them up, and tie firmly.
In a saucepan, place any remaining bacon scraps, vegetable trimmings, and herbs.
Lay the liver rolls on top, season with salt and pepper, cover with boiling water, and simmer.
