Sourdough Starter

Ingredients:
2 Cups Warm Water
1 TBSP Sugar or Honey
1 TBSP Active Dry Yeast
2 Cups All-purpose Flour

Instructions:
1. In a large glass or ceramic bowl, stir honey or sugar into warm water until dissolved. Stir in yeast.
2. Slowly add flour to mixture, whisking to combine, and cover with a towel or dishcloth. Use a towel rather than plastic wrap so the wild yeast in your kitchen can "catch onto" the starter, but be sure to use a towel that you don't mind getting dirty. Leave in a warm place to develop. If you don't have a warm place, it should be fine, as my kitchen was cool when I made my starter.
3. Let your starter sit out for 2-5 days, stirring once per day to reincorporate the liquid that will settle on top. Once your starter has stopped bubbling and has developed a sour aroma, stir it once again and place in an airtight container in the refrigerator until ready to use.

Sourdough starter needs to be fed about once every two weeks. To feed your starter, you first need to remove one cup. Use this cup of starter for baking, Then, feed your existing starter with 1 cup of all-purpose flour and 1/2 cup water. Stir until smooth and let sit, covered, at room temperature for about 12 hours before placing back in the refrigerator.
