From the Test Kitchen
*Test Kitchen Tip:
To make 3/4 cup sour milk, place 2 teaspoons lemon juice or vinegar in a glass measuring cup. Add enough milk to make 3/4 cup total liquid; stir. Let the mixture stand for 5 minutes before using.
**Test Kitchen Tip:
If you like, you can bake the cake in a 9x2-inch round cake pan for about 45 minutes.
Candied Citrus Slices
- Cut clementines, lemon, and, if desired, kumquats into 1/8-inch slices (if you have trouble cutting kumquats into slices, instead cut them in half). Remove any seeds; set slices aside. In a large skillet or medium saucepan combine sugar and the water. Cook and stir over medium-high heat until mixture begins to simmer and is clear. Reduce heat to medium. Add citrus slices; simmer for 15 to 20 minutes or until slices are softened, turning occasionally. Remove from heat; cool. Drain slices on a wire rack; if necessary, pat dry with paper towels.
- In a large mixing bowl beat butter with an electric mixer on medium speed until smooth. Gradually add 1 cup of the powdered sugar, beating well. Slowly beat in 2 to 3 tablespoons milk, the vanilla, and, if desired, lemon peel. Gradually beat in remaining sugar. Beat in enough additional milk to reach spreading consistency. If desired, tint with food coloring.
