A little about my starter

The Lost Boys: A few years ago I tried to create a couple of starters from flour, water and air. These were known as Peter Pain1 Mk1 and Mk2. The fact I tried more than once says it all - making a sourdough starter from scratch isn’t easy. Both sadly never made anything more than a boule or two, all of which resembled discuses2. So I resorted to plan B.

Peter Pain Mk3: Around October 2019 I purchased a small envelope of dried sourdough starter from John Kirkwood3 via his website I’ve fed it almost every week and have used it to bake some great bread (if I do say so myself) and a wide array of other things. It is still going strong and I highly recommend getting a well established starter if you want to take up baking sourdough.

Looking after a Sourdough Starter

I recently changed how I look after my starter and now use a technique called the scrapings method which I learnt from Bake with Jack4. I have included both methods below as they both have a use.

Before getting to the methods, there are a few things that are useful to know when looking after a starter:

What is a Feed?

A feed simply means giving the starter new flour and water so it can continue to grow. The ratios may vary depending on your answers above, but for me (1:1 ratio) I feed as follows:

  1. Mix 1 part starter with 2 parts filtered water (doesn’t have to be perfectly mixed)
  2. Add 2 parts flour and mix until no dry flour is visible
  3. Scrape down the sides of your container to stop starter drying onto the sides
  4. Loosely cover and put in a safe place

This same formula is used for making a levain, which is then used to make bread.

(#1) The Scrapings Method

This method is less wasteful since you don’t really discard any starter. It also means you don’t have to find a load of recipes to use up your discard and is very easy to pull off.

  1. A day or so before you wish to bake with the starter, feed the starter so that it is active. The first time you do this you will have to discard, but subsequently you should have the perfect amount for a feed in the jar.
  2. On bake day, use the active starter straight from the jar to make your bread.
  3. After using the starter for baking, simply scrape down the sides of the jar and put it in the fridge ready for next week.
  4. When next week comes around you can start at step one again.


(#2) The Discard Method

This method is great if you want to make lots of things with the discard (more on that later). It is also useful if you bake less frequently than once a week. I still use this method when I don’t bake in a given week and I need to recharge my starter, or if I don’t use the full amount of starter I made.

  1. Weigh the jar with the starter in and deduct the jar weight. This is how much starter you have. From this calculate how much to discard.
    • Example: Total weight = 500g and jar weight = 250g, then starter weight = 250g, so discard = 200g to have 50g for feed.
    • Example 2: Total weight = 410g and jar weight = 250g, then starter weight = 160g, so discard = 110g to have 50g for feed.
  2. “Discard” the amount you calculated.
    • For me this means putting it into a bowl and into the fridge so I can use it for something else. You could bag and bin it though if you aren’t going to use it.
    • You can also use this “discard” to make a levain for baking or if the discard is active, even use that directly to bake.
  3. Perform a feed and put the starter back in the fridge.

Example (No Bake):

Example (Bake):

Both methods have a place and I used both when it’s needed. I try to waste as little as possible by using the scrapings method predominantly, but something I don’t bake and need to feed to keep everything alive and that is where the discard method comes in handy.
