Using Dried Sourdough

On a recent visit to my local Polish shop I came across packets of dried sour dough.

I had never seen these before and bought a couple to try them out.

There was a recipe printed on the back of the packet and this is what I used.

  • I have noticed many Dr. Oetker products in Poland and in England.
  • I thought the company name was made up but have found this is not so.
  • Doctor August Oetker was a German chemist and was one of the people who invented baking powder.
  • He started a company in 1891 and the first product sold was Bakin, which was a measured amount of baking powder to be added to 500g of plain flour when making a cake. 
  • His family still run what is now a multi-national company.

Ingredients

  • 150g rye flour
  • 350g strong flour
  • 1 teaspoon of granulated sugar
  • 1½ teaspoon salt
  • 1 packet of dried sourdough
  • 1 tablespoon of dried yeast
  • 400ml of lukewarm water (approx)
  • *
  • 2 tablespoons of sunflower oil
  • 2 tablespoons of seeds eg – sesame, linseed, caraway
  • *
  • 1 teaspoon of sesame or caraway seed

Method

  • In a large bowl mix the rye flour, strong flour, sugar, dried sour dough and the yeast.
  • Slowly add the water to get a soft dough that you can knead.
