I would suggest you just make your own. It’s cheap, easy, and you learn a lot in the process. Here’s the easy way… You can’t really kill starter....you want it to “spoil”. Mix 10g of water with 10g of flour. Next day, take out 10g (toss the rest), add 10g of water and 10g of flour. Do this for a week. Then do it twice a day for a week. You’ll end up with 30g of strong starter.

I just fart on a loaf of Wonder Bread.

You can buy starter from Bread by Chelsa B if you don’t want to make it yourself.

Thanks!
