Instructions
First Day - Part 1
Add the 15g of dried sourdough starter to your glass jar.
Pour in 30g of filtered water and stir well.
Cover loosely with a lid and place in a warm location for three hours. The dried starter should dissolve.
27˚C is the optimal temperature which can be achieved by sitting the jar in the oven. In cool climates, you may want to place it in the oven with the oven light on.
First Day - Part 2
At the end of the three hours, mix in 15g of your choice of flour.
Stir well and cover loosely again.
This time leave in a warm spot for 12-14 hours.
At the end of this, there may not be much activity at all.
Second Day
Once the 12-14 hours is up, it is time to feed the starter again.
Without discarding anything, add another 15g of flour and 15g of water and mix well.
Replace the lid and place in a warm location.
Third Day
It is time to feed the starter again.
Without discarding anything, add another 15g of flour and 15g of water and mix well.
Replace the lid and place in a warm location.
At the end of this time, you may begin to see signs of activity such as small bubbles and a slightly sour smell.
Fourth Day
Discard all but 15g of your sourdough starter.
Add 30g flour and 30g water to the 15g starter.
Replace the lid and place in a warm location for 12 hours.
Fifth Day
The starter should be starting to get very active. It should be starting to double in size, be quite bubbly and smell sweet with just a small hint of sourness.
Do one more discard of all but 15g of your sourdough starter, then add the 30g of water and 30g of flour and mix well.
Keep an eye on your starter and see how long it takes to double in size.
When it is at its peak, discard and feed again like you did earlier in the day.
Sixth Day
Your starter is activated and ready to be fed on a normal feeding schedule.
You always want your starter to be thick, like a thick pancake mix consistency. Sometimes it may have a liquid, known as hooch on time and this is fine. Just mix it in and feed like normal.
