• Krispy Kreme Doughnuts
Makes 10 doughnuts

3/4 cup warm water (100 degrees to 110 degrees F)
1 package (2 1/4 teaspoons) active dry yeast
2 teaspoons granulated sugar
1 cup all-purpose flour
3/4 cup plus 1 tablespoon cake flour
3/4 teaspoon salt
1 egg yolk
1 tablespoon nonfat milk
1/2 teaspoon vanilla extract

For Glaze:
1/3 cup water
3/4 cup granulated sugar
1/2 cup powdered sugar
1/4 teaspoon meringue powder
pinch salt

6 to 10 cups vegetable shortening (as required by your fryer)

1. Dissolve the yeast and sugar in the warm water. Let solution stand for 5 minutes or until it becomes foamy on top. Make sure the water isn't too hot to avoid killing the yeast.

2. Sift the flour and salt together into a large bowl. Beat egg yolk in a small bowl, then stir in the milk and vanilla. Pour the yeast solution into the bowl with the egg and milk, and stir. Make a well in the center of the flour, then pour the yeast solution into that well. Stir by hand gently with a wooden spoon from the middle, slowly bringing in more flour until all ingredients come together into a ball -- the dough will still be too sticky to handle at this point. Cover the bowl and let it sit in a warm place for 30 to 45 minutes or until the dough doubles in size.

3. While the dough is rising, cut 10 4 x 4-inch squares of wax paper and arrange them on two rimmed baking sheets. Each doughnut will rise on its own square of wax paper, and the rimmed baking sheet will allow you to wrap a large sheet of foil over the doughnuts without the foil touching the doughnuts. Sprinkle a little flour on each of the squares of wax paper.

4. Use flour on your hands to transfer the dough to a floured surface. Sprinkle a little flour on top of the dough, and then gently roll out the dough until it's about 1/2-inch thick. Use only the amount of flour needed to allow you to handle the dough. Use a 3-inch biscuit cutter to cut out circles of dough, then use a lid from a plastic soda or water bottle (about 1 1/8-inch diameter) to cut the holes. Carefully place each doughnut on a square of wax paper with the most floured side of the doughnut down on the wax paper. Cover the doughnuts with large sheets of foil and let them sit for 45 minutes in a warm place until the doughnuts have puffed up to at least twice their original size.

5. While the doughnuts rest, make the glaze by combining water and granulated sugar in a small saucepan over medium heat. Bring mixture to a boil and then reduce heat and simmer for 1 minute, or until the solution is clear. Pour hot sugar solution into a medium mixing bowl, add the powdered sugar, meringue powder and a pinch of salt, then use an electric mixture and mix for 2 minutes on high speed. Cover this bowl with plastic wrap until you need it.

6. As the doughnuts rise, heat vegetable shortening in a fryer to 375 degrees F.

7. When the doughnuts have doubled in size, carefully transfer 2 or 3 doughnuts at a time to the hot shortening. Turn each doughnut over onto the palm of your hand, carefully remove the wax paper and then drop it into the oil. Fry for 1 minute, flip the doughnut with the handle of a wooden spoon, and continue frying for an additional minute. Remove donuts to a cooling rack for one minute.

8. After a minute on the cooking rack, spoon the glaze over the top of each doughnut so that it runs down the sides and off onto the plate below the cooling rack. In between each glazing stir the glaze so that it stays smooth. If the glaze begins to thicken, stir in just a little bit of hot water to thin it out. Let the glazed doughnuts cool for at least 5 minutes before eating. Don't store doughnuts in a sealed container or moisture from the doughnuts will melt the glaze. Instead store them covered loosely with aluminum foil. Stored this way the doughnuts will be good for about 1 day.

Todd's Tips:
As you can guess, the main ingredient in a Krispy Kreme doughnut is wheat flour, but there is also some added gluten, soy flour, malted barley flour, and modified food starch; plus egg yolk, non-fat milk, flavoring, and yeast. I suspect a low-gluten flour, like cake flour, is probably used in the original mix to make the doughnuts tender, and then the manufacturer adds the additional gluten to give the doughnuts the perfect framework for rising. I tested many combinations of cake flour and wheat gluten, but found that the best texture resulted from cake flour combined with all-purpose flour. I also tried adding a little soy flour to the mix, but the soy gave the dough a strange taste and it didn't benefit the texture of the dough in any way. I also excluded the malted barley flour and modified food starch from the recipe since these are difficult ingredients to find. These exclusions didn't seem to matter because the real secret in making these doughnuts look and taste like the original lies primarily in careful handling of the dough. The dough will be very sticky when first mixed together, and you should be careful not to over mix it or you will build up some tough gluten strands, and that will result in chewy doughnuts. You don't even need to touch the dough until it is finished with the first rising stage. After the dough rises for 30 to 45 minutes it will become easier to handle, but you will still need to flour your hands. Also, be sure to generously flour the surface you are working on when you gently roll out the dough for cutting. When each doughnut shape is cut from the dough, place it onto a small square of wax paper that has been lightly dusted with flour. Using wax paper will allow you to easily transport the doughnuts (after they rise) from the baking sheet to the hot shortening without deflating the dough. As long as you don't fry them too long -- 1 minute per side should be enough -- you will have tender homemade doughnuts that will satisfy even the biggest Krispy Kreme fanatics.

• McDonald’s Vanilla Iced Coffee
Makes one 16-ounce serving

1/4 cup Torani vanilla syrup
1/4 cup half-and-half
1 cup cold coffee

1. Fill a 16-ounce cup with ice.

2. Pour the vanilla syrup over the ice, followed by the half-and-half and cold coffee. Serve with a straw.

Todd's Tips:
The Vanilla Iced Coffee appears to be a standout selection at Mickey D's, and a home clone is simple after you get your hands on some Torani vanilla syrup. You can find Torani vanilla syrup in many grocery stores near the coffee, or at well-stocked liquor and bar supply stores. Brew up some coffee, chill it, then pour these three ingredients over ice in a 16-ounce glass. The taste of your finished drink will be determined by the quality of your coffee (McDonald's has its own beans), so be sure to brew your best stuff. The better the coffee you start with, the better your clone will taste.
