Kensington Market Sourdough Starter SUPER ACTIVE!

The Internet's Favorite Sourdough Starter!

This diabolical starter traces its roots back to the San Francisco gold rush (really!!) but has been living and mingling with Kensington Markets eclectic denizens for the past several years, and has now mutated into its own beast! it’s been in continuous use since 1850!

This starter makes great bread.

It’s a strong and versatile starter and i’m happy to share.

you will get a packet of dry starter and a printout of step by step instructions to bring it to life. It will take 3-7 days to get it fully active. I have included some general instruction for maintaining the starter and getting started with your first loaves, as well as links to some of my favourite recipes!

it’s pretty fool proof and you will be baking amazing loaves in no time. It’s a great feeling to watch this starter bursting out of the jar as you are getting ready to start baking — I defy you to make something with this that doesn’t taste great.

No yeast required and this starter will last for a lifetime of bread with a simple feeding schedule of flour and water.

Quick delivery to Canada and the USA and around the world. I will process your order the same business day if at all possible.

I work really hard to keep this incredible starter happy and healthy and I hope you will love it as much as I do. Happy baking! Ben

So so happy with this starter! Arrived fairly quickly and was packaged well. The instructions are easy to follow and everything worked exactly as promised. I’m an absolute beginner with sour dough so really appreciated the extra notes about starter care and recipe suggestions. Such a strong, active starter!

First time doing sourdough started. I was so anxious and nervous but their instructions couldn’t be more clear. Made pancakes and two loafs turned out so good! Thank you so much for your started. Also the story behind it was amazing to learn. :) will order again and highly recommend.

The seller is amazing to work with. Great communication. I also appreciated the detailed notes that came with my order. This will be my first time making my own sourdough and I cannot wait. One of my friends had purchased this same product and I got tired of looking at all her awesome outcomes from afar :).
