Step 1Dissolve the yeast in 1/2 cup of the warm water in a deep glass or plastic container. Stir in the remaining warm water, flour and sugar. Beat until smooth. Cover loosely with plastic wrap. Do not refrigerate.
Step 1On days one, two, three and four, stir the starter.
Step 2On day five, add 1 cup of milk, 1 cup of flour and 1 cup of sugar. Stir.
Step 3On days six, seven, eight and nine, stir the starter each day.
Step 4On day 10, add the remaining 1 cup of milk, 1 cup of flour and 1 cup of sugar. Stir. The starter is ready to use. This makes 3 cups of starter. If you want, pour 1 cup of starter into two containers to give away, and save 1 cup to begin the process over again.
Step 1Heat the oven to 350 degrees. Lightly grease 2 (9x5-inch) loaf pans.
Step 2Sift together the flour, sugar, baking powder, cinnamon, baking soda and salt. Set aside.
Step 3In a large mixing bowl, stir together the Amish Friendship Starter, eggs, oil and vanilla. Gradually stir in the sifted ingredients until just blended. Stir in the nuts and apples. Divide the batter evenly between the pans.
Step 4Bake until a toothpick inserted into the center of a loaf comes out clean, about 1 hour 10 minutes.
