1Cut cold butter or margarine and cream cheese into bits. In food processor pulse flour, salt, butter or margarine, cream cheese and sour cream until crumbly.
2Shape crumbly mixture into four equal disks. Wrap each disk and chill 2 hours or up to 2 days.
3Combine sugar, cinnamon, chopped walnuts, and finely chopped raisins (may substitute miniature chocolate chips for raisins).
4Roll each disk into a 9 inch round keeping other disks chilled until ready to roll them. Sprinkle round with sugar/nut mixture. Press lightly into dough. With chefs knife or pizza cutter, cut each round into 12 wedges. Roll wedges from wide to narrow, you will end up with point on outside of cookie. Place on ungreased baking sheets and chill rugelach 20 minutes before baking.
5Preheat oven to 350 degrees F (180 degrees C).
6After rugelach are chilled, bake them in the center rack of your oven 22 minutes until lightly golden. Cool on wire racks. Store in airtight containers...they freeze very well.
7Variations: Before putting the filling on the dough, use a pastry brush to layer apricot jam as well as brown sugar. Then add the recommended filling. You may also make a mixture of cinnamon and sugar and roll the rugelach in this prior to putting them on the cookie sheets.
