In a small bowl or measuring cup dissolve the yeast in the warm water. Allow to stand for about 10 minutes.
In a large glass or plastic bowl combine the dry ingredients; 1 cup of sugar, 1 cup of all purpose flour
Blend the dry ingredients using a wooden spoon
Now slowly add 1 cup of milk and the dissolved yeast to the dry mixture, stirring well after each addition
Continue to stir until all the lumps are gone.
Cover the bowl loosely with plastic wrap and allow to stand until the mixture is bubbly.
Once your starter mixture is bubbly, pour it into a gallon size plastic food storage bag on which you have written 'Day 1' along with the date
The squishing process begins.
Day 2 Squish the bag
Day 3 Squish the bag
Day 4 Squish the bag
Day 5 Squish the bag
Day 6 Add 1 Cup each all purpose flour, granulated sugar and milk. Squish all the lumps out (I mix the flour, sugar and milk in a glass bowl using a plastic whisk THEN pour into the starter)
Day 8 Squish the bag
Day 9 Squish the bag
