Cream together the sugar, salt, and shortening or butter on medium-high speed in an electric mixer with a paddle attachment (or use a large metal spoon and mixing bowl and do it by hand); if you are using powdered milk, cream the milk with the sugar, and add the water with the flour and yeast. Whip in the egg and lemon extract/zest until smooth. Then add the flour, yeast, and milk. Mix on low speed (or stir by hand) until the dough forms a ball. Switch to the dough hook and increase the speed to medium, mixing for approximately 10 minutes (or knead by hand for 12 to 15 minutes), or until the dough is silky and supple, tacky but not sticky. You may have to add a little flour or water while mixing to achieve this texture. Lightly oil a large bowl and transfer the dough to the bowl, rolling it around to coat it with oil. Cover the bowl with plastic wrap.
Ferment at room temperature for approximately 2 hours, or until the dough doubles in size.
Mist the counter with spray oil and transfer the dough to the counter.
(A) Roll out the dough with a rolling pin, lightly dusting the top with flour to keep it from sticking to the pin. Roll it into a rectangle about 2/3 inch thick and 14 inches wide by 12 inches long for larger buns, or 18 inches wide by 9 inches long for smaller buns. Don´t roll out the dough too thin, or the finished buns will be tough and chewy rather than soft and plump. (B)Sprinkle the cinnamon sugar over the surface of the dough and (C) roll the dough up into a cigar-shaped log, creating a cinnamon-sugar spiral as you roll. With the seam side down, cut the dough into 8 to 12 pieces each about 1 3/4 inches thick for larger buns, or 12 to 16 pieces each 1 1/4 inch thick for smaller buns.).
For cinnamon buns, line 1 or more sheet pans with baking parchment. Place the buns approximately 1/2 inch apart so that they aren´t touching but are close to one another.
For sticky buns, coat the bottom of 1 or more baking dishes or baking pans with sides at least 1 1/2 inches high with a 1/4 inch layer of the caramel glaze. Sprinkle on the nuts and raisins (if you are using raisins or dried fruit.) You do not need a lot of nuts and raisins, only a sprinkling. Lay the pieces of dough on top of the caramel glaze, spacing them about 1/2 inch apart. Mist the dough with spray oil and cover loosely with plastic wrap or a food-grade plastic bag.
Proof at room temperature for 75 to 90 minutes, or until the pieces have grown into one another and have nearly doubled in size. You may also retard the shaped buns in the refrigerator for up to 2 days, pulling the pans out of the refrigerator 3 to 4 hours before baking to allow the dough to proof.
Preheat the oven to 350°F (175°C) with the oven rack in the middle shelf for cinnamon buns but on the lowest shelf for sticky buns.
Bake the cinnamon buns for 20 to 30 minutes or the sticky buns 30 to 40 minutes, or until golden brown. If you are baking sticky buns, remember that they are really upside down (regular cinnamon buns are baked right side up), so the heat has to penetrate through the pan and into the glaze to caramelize it. The tops will become the bottoms, so they may appear dark and done, but the real key is whether the underside is fully baked. It takes practice to know just when to pull the buns out of the oven.
For cinnamon buns, cool the buns in the pan for about 10 minutes and then streak white fondant glaze across the tops, while the buns are warm but not too hot. Remove the buns from the pans and place them on a cooling rack. Wait for at least 20 minutes before serving. For the sticky buns, cool the buns in the pan for 5 to 10 minutes and then remove them by flipping them over into another pan. Carefully scoop any run-off glaze back over the buns with a spatula. Wait at least 20 minutes before serving.
White fondant glaze for cinnamon buns.
Cinnamon buns are usually topped with a thick white glaze called fondant. There are many ways to make fondant glaze, but here is a delicious and simple version, enlivened by the addition of citrus flavor, either lemon or orange. You can also substitute vanilla extract or rum extract, or simply make the glaze without any flavorings.
Sift 4 cups of powdered sugar into a bowl. Add 1 teaspoon of lemon or orange extract and 6 tablespoons to 1/2 cup of warm milk, briskly whisking until all the sugar is dissolved. Add the milk slowly and only as much as is needed to make a thick, smooth paste.
When the buns have cooled but are still warm, streak the glaze over them by dipping the tines of a fork or a whisk into the glaze and waving the fork or whisk over the tops. Or, form the streaks by dipping your fingers in the glaze and letting it drip off as you wave them over the tops of the buns. (Remember to wear latex gloves.).
Caramel glaze for sticky buns.
NOTE: you can substitute the corn syrup for any neutral flavor syrup, like cane syrup or gold syrup.
In the bowl of an electric mixer, combine 1/2 cup granulated sugar, 1/2 cup firmly packed brown sugar, 1/2 teaspoon salt, and 1/2 pound unsalted butter, at room temperature.
Cream together for 2 minutes on high speed with the paddle attachment. Add 1/2 cup corn syrup and 1 teaspoon lemon, orange or vanilla extract. Continue to cream for about 5 minutes, or until light and fluffy.
Use as much of this as you need to cover the bottom of the pan with a 1/4-inch layer. Refrigerate and save any excess for future use; it will keep for months in a sealed container.
