Prepare the syrup as the sugar is poured into water, add vanilla and lemon and leave on low heat until the sugar melts and the syrup thickens. Eggs and sugar is broken down to graying. Soda put in yogurt, mix and in December added to the mixture of eggs and sugar. Begin to add the flour. Mixed mixture is thick (like a cake for cake). Pour into greased and sprinkled with flour pan. Bake until golden in an oven preheated to 180 degrees. The baked cake is left to cool a little and pour the syrup. Allow to cool several hours.
