I got a recipe from a friend for Scandinavian Kringles - she said it was a favorite of hers that her mom made - I have not yet tried it, but maybe it is similar to the one you lost:
Crust; 1 cup flour, 1/2 cup margarine or butter, chilled, 2 Tbsp. ice water
Puff Topping: 1 cup water, 1/2 cup margarine or butter, 1 cup flour, 3 eggs, 1/2 tsp almond extract
Frosting: 1 cup powdered sugar, 1 Tbsp. softened margarine or butter, 1/2 tsp. almond extract, 2 - 3 Tbsp. milk or cream, sliced almonds or chopped nuts
Heat oven to 350'F In small bowl add flour and margarine. Using a pastry blender, cut margarine into flour until particles are size of a pea. Sprinkle with water, 1 Tbsp at a time. Stir with fork just until soft dough forms. Divide dough in half. On ungreased cookie sheet, press each half into 12x3 inch strip. In medium saucepan, heat water and 1/2 cup margarine to boiling,. Remove from heat, immediately stir in 1 cup of flour until smooth. Add eggs 1 at a time, beating until smooth after each addition. Stir in 1/2 tsp. almond extract. Spoon 1/2 of batter over each crust, spreading to 3/4 inch from edges. Bake at 350' for 50 -60 minutes until golden brown and puffy. Immediately remove from pan, cool. Topping will shrink and fall. In small bowl, blend all frosting ingredients, except nuts, until smooth. Spread on cooled kringles. Sprinlkle with nuts. Cut each into 8 or 10 slices. 16 - 20 slices of kringle
Enjoy!
