Reducing a sourdough recipe

My mom is recently widowed and now living alone. She loves fresh bread (right?).
Making a 500 gram loaf and freezing half is not as good as having a fresh loaf of yummy sourdough. I’m getting great results with my weekly classic or rye sourdough loaves and we are wondering about making a smaller, 250 gram loaf.
Can I just cut all the ingredients down by 50% or is there some other magic in regards to bread baking?

Thanks!

Yes. It’s as simple as that!

The only thing to watch out for is the baking.

Oh, magic! Yes, watching the bake time will be important.
Thanks so much!

If you’re halving or doubling it’s very easy. There is an easy formula which allows one to start off with one size loaf and convert to any size you want.

New Size divided by Old Size and then Multiplying every ingredient by the number.

So say you have a 900g loaf and you want an 820g loaf. Not easy as one can’t just half or double. However if we plug the numbers into the formula…

820 / 900 = 0.9111 (go to 4 decimal places)

Then you multiply every ingredient by 0.9111 and just round each answer to the nearest whole number.
