Preface: Like most Italian women of those days, Nunziata DiRenzo (born in 1897) of Gambatesa, Italy, and Camden, New Jersey, never wrote down a recipe for the biscotti she made. But once she told her oldest daughter how she made them.
Nunziata's directions began with a (5 lb) bag of flour, two cartons (2 dozen "large") eggs, 1/2 (of a 5 lb) bag of sugar, a (1 lb) container of solid vegetable shortening, 12 teaspoons of baking powder, and 4 ounces of flavoring. Nunziata DiRenzo was less than 4 feet 10 inches tall and slightly built, and, if you are strong, you can mix these ingredients together in a tall spaghetti pot like she did. If not, the following smaller recipe is based on her directions.
Note: these Italian biscotti are hard biscuits, not light and airy.
Nunziata DiRenzo's Biscotti Recipe
Ingredients [Metric equivalents]
• 3 cups flour, plus about 1 cup more flour
• 1 and 1/2 tsp baking powder
• 1/4 cup (generous) solid vegetable shortening, gently melted over low heat and then allowed to cool a bit
• 4 large eggs
• 1 cup (generous) sugar
• Flavoring: a generous shot glass of liqueur or whiskey or a bit of wine (or 1 tsp vanilla or almond extract is always safe)
• Greased baking sheet(s), at least one 16-inch x 12-inch sheet or two somewhat smaller sheets
• Oven preheated to 350 to 400 degrees F.
Method
In a large bowl, beat up the eggs and the sugar and the flavoring together well; then slowly beat in the melted vegetable shortening. In another bowl mix the 3 cups of flour and the baking powder together well; then stir them into the liquid. Now slowly add as much of the rest of the flour as is needed to make a very soft dough. (All this can be done with a wooden-spoon.)
Turn the mixture out onto a well-floured surface and very gently "knead" it into a smooth, shiny ball of dough. This dough should always be slightly sticky, so try to use the least amount of flour needed to keep it under control.
Divide the dough in half. Under your hands form the halves into rough loaves and lay them length-wise on the baking sheet(s). Smooth out the loaves with lightly floured hands; they should be about 2 inches wide and 1 inch high (1 inch = 2.5 cm.), with rounded edges on top. They will spread a little when baking; so do not crowd them.
Bake the loaves in the oven for about 20 minutes or until the tops of the loaves are quite firm when pressed with the fingers. They should be fully baked inside. (At about 10 minutes, check that the bottoms of the loaves are not burning; you may need to reposition the baking sheet(s) in the oven.)
Remove the loaves to a cutting board and, beginning at the center, cut them width-wise in slices about 1/2 inch thick. (If the first slice reveals that the dough is not fully baked inside, then immediately return the loaves to the oven.) A serrated-knife works best to slice these loaves, but serrated-knives are very dangerous.
Lay the slices on their sides on the baking sheet(s) and return them to the oven for about 5 minutes. Then lay the slices on their other sides and bake about 5 minutes more. Finally, if necessary, stand the slices up and bake them for about 5 minutes more, or until they are thoroughly dried out inside.
Thoroughly cool the slices on cooling racks. There should be about 36 twice-baked cookies. They can be stored in a paper bag or in a cookie tin.
You may be able to double this recipe. But remember that it takes much more space to twice-bake the slices than it does to bake the loaves; so it will take more time unless you have extra baking sheets.
Biscotti Recipe Notes
It is not possible to give exact baking times. Whatever times are needed for the biscotti to be fully baked and then dried out are the correct times.
Do not use too large a bowl for mixing the ingredients, because this will make it difficult for you to judge how much flour to add. (Nunziata DiRenzo used a wooden spoon and the pot for boiling water for spaghetti, but even in old age she worked with 5 lbs of flour at a time.)
Nunziata DiRenzo used to line her baking sheets with wax paper, to prevent the dough from sticking. Wax paper tends to smoke at high temperatures (Parchment paper works well); she set her oven at 400° F. The melted and then cooled vegetable shortening may have been a replacement for lard; vegetable oil may not give the same results, because it is essential that there be no taste of oil in the finished biscotti.
You must learn by trial and error what to use and what to do to get the results you want. There is no royal road to biscotti making. (But even when you make mistakes these cookies taste good.)
Metric Translations
- tsp = use a coffee spoon
- 1 cup flour = 4 and 3/4 dry oz = 135 grams
- 1 "large" egg = 2 dry oz = 60 grams
- 1/4 cup vegetable shortening = 60 grams
- 350° to 400° F. = 175° to 200° C.
- 16-inch x 12-inch = 40 cm. x 30 cm.
The measurements given on this page are all more-or-less, but try to stay reasonably close; e.g. too much sugar will give the biscotti a sugar-cookie crispness, and too much flour will make both an elastic dough that balloons into odd shapes in the oven and a less flavorful biscuit.

"Historical Notes"

In the dialect of Molise biscotti is "bisgótt". Nunziata DiRenzo's younger children gave the dialect word an English-language plural, and so to their children these were known as "Grandmom's biscotts". Some of Nunziata's children used to eat these biscotti for breakfast, spread with butter and then dipped into American coffee (This was when children used to drink coffee for breakfast).
Usually "twice-baked" bread, however, was eaten for breakfast; either Giovanni Valente brought this home from the bread bakery where he worked, or they dried day-old bread in their oven at home. At the Italian bakeries in the old days, the bakers used to slice unsold day-old Italian loaves and thoroughly dry the slices in their ovens; -- these slices were about the size of sliced-in-half Italian rolls; they were hard, not brittle. The old Italians used to buy bags of this twice-baked bread. In Gambatesa, people used to put these dry bread slices in old flour bags and take them to the farm to eat when no fresh bread was baked.
During the Great Depression, on Berkley Street in Camden, the children would put butter on the twice-baked bread (hard toast) that their father Giovanni brought home and dip it in their cocoa for breakfast, and many of the neighborhood children would eat with them (Unlike many of his neighbors, because he was a bread baker, Giovanni Valente always had work and food). The cocoa was made on the stove with milk and sugar.
Nunziata DiRenzo also used sometimes to make what in dialect she called a bizz', i.e. pizza. This was lean bread dough (pane comune: flour, water, yeast and salt), pressed out not-too-thick-or-thin in a half-sheet pan (but not forced into the corners) and sparsely dressed with either broken whole tomatoes or Italian sausages which Nunziata cooked before she vigorously worked them into the dough before baking.
Nunziata DiRenzo and her mother Maria Vittoria d'Alessandro also used to make the taralli of Gambatesa, unsweet biscuit rings made in an unusual way, and Biscotti con le uova.
Note:: when I sent some of these biscotti to our cousin in Geneva (Christmas 2006), Angelo Abiuso told me that they taste the same as in Gambatesa, but that in Gambatesa when they make this type of biscotti they make them flatter, like the biscuits called Maletagliate in the dialect of Gambatesa (elsewhere called cantucci).
