How I Started a Traditional Sourdough Starter (Without Wasting a Ton of Flour)

For the longest time, I wanted to try making a traditional sourdough starter… but every recipe I found told me to use 100 grams of flour at a time and discard half of it every single day.

Maybe it’s just me, but that felt so wasteful.

All I could think about was perfectly good flour going straight into the trash.

So I kept putting it off.

Finding a No-Discard Method

After going down a sourdough rabbit hole (as one does), I came across the no-discard method from She Bakes Sourdough and decided to give it a try. The biggest lightbulb moment?

You do not need a massive quantity of flour to create a healthy, active starter.

You just need the correct ratios.

That completely changed the game for me.

Instead of feeding 100g at a time, I started very small — and it worked.

Starting Small (Like, Really Small)

I keep a tiny starter. Most days it’s around 9 grams total.

Here’s exactly what I do:

• Keep 3 grams of starter

• Add 3 grams flour

• Add 3 grams water

That’s it.

No giant jar.
No huge discard.
No guilt.

When I’m ready to bake, I simply build it up a few days before. Otherwise, I keep it small and manageable.

If you’ve been avoiding sourdough because it feels overwhelming or wasteful, this is your sign that it doesn’t have to be.

The Winter Struggle (Ohio Edition)

Now… here’s where things got interesting.

I started this in the winter here in Ohio, and my starter wasn’t quite doubling like it was supposed to. It would rise a little… but not enough to feel confident.

Instead of scrapping the whole thing, I did some research.

One tip that kept popping up? Try rye flour.

So I swapped out my regular flour for rye during a feed.

The very next day, there was a noticeable difference.

It was bubbly.
It was rising.
It was alive.

And from that point on, we were off to the races.

What I Learned

Here’s what I wish someone had told me before I started:

• You don’t need large quantities to create a healthy starter.

• Ratios matter more than volume.

• Temperature plays a huge role (especially in winter).

• Rye flour can give your starter the boost it needs.

• You can keep your starter tiny and build it up only when needed.

Sourdough doesn’t have to mean dumping flour in the trash every day. It can be simple. Low waste. Manageable.

And honestly? Kind of addictive once it gets going.

If you’ve been thinking about starting sourdough but feel intimidated, start small. Use the right ratios. Adjust for your environment. And don’t be afraid to experiment.

If you try it, let me know — I’m always up for talking sourdough.
