Raisin Paste*
Measure raisins and water into saucepan and heat to simmer. Simmer until raisins are very tender. Drain water and turn raisins into a food processor. Process until smooth. (The paste should be very thick and measure about 1/2 cup). Set aside.
Pecan Streusel
Combine butter and all dry ingredients in mixer bowl. With paddle, mix on medium speed until crumbly. Spread on parchment-lined sheet pan and bake at 350ºF until lightly golden brown and crisp. Let cool and break into small pieces.
Batter
Preheat oven to 300ºF. Grease 3 loaf pans.
Cream butter and sugar on medium speed until light and fluffy. On low speed, add eggs one at a time, beating after each addition. Sift dry ingredients together and add alternately with sour cream mixing on low speed. Stir in vanilla. Divide batter in half. Fold raisin paste, diced apples and raisin juice concentrate into one-half of batter and reserve. Fold streusel and raisins into remaining half of batter; divide to fill bottoms of 3 loaf pans about 1/3 full. Divide and spoon reserved batter down center of each. Then, divide and spoon on remaining streusel batter to fill pans to 2/3 full. Bake at 300ºF in convection oven (350°F in conventional oven) for approximately 50 to 60 minutes. Let cool slightly and remove from pans, cool completely on a wire rack.
Note: Commercially prepared California raisin paste and raisin juice concentrate are available from foodservice and industrial suppliers.
