I was getting ready to ship off the Danish cookbook to Ted when I remembered that you had asked for a recipe for Danish pastry. Here's a gen-u-wine one, several variations and a short recipe for Sand Cake that got snagged with the Danish recipe.
Mix the butter and sugar, add the eggs one at a time, and finally the sifted flour and vanilla extract. Bake in a moderate oven about 1 hour, or until golden brown. If baked only 45 min. The cake will be underdone but tastier.
