Hello Reader,

Our 10,000 Jar Challenge is officially LIVE! And I would absolutely love to see your jar of sauerkraut or kimchi posted to the challenge page.

Whether it’s your very first batch or your fiftieth, this challenge is for anyone who wants to join in, have fun, and celebrate the power of fermentation—one jar at a time.

🫙 Post your jar here → 10KJarChallenge​

Already seeing bubbles in your batch? Snap a pic and share your ferment in action!

Still flipping through the book for your first recipe? Perfect—pick one, get chopping, and join the movement.

We’re aiming to collect 10,000 jars and show the world that fermentation is fun, accessible, and incredibly rewarding.

The page is a bit bare now, but when we hit 100 jars, we’ll do a giveaway!

Thank you for your patience as we get everything up and running! Your photo won’t appear on the page immediately—I’ll be uploading submissions manually on a regular basis.

💥 One lucky winner will receive a signed copy of Mouthwatering Sauerkraut [+Kimchi], a set of fermentation springs, and a package of gochugaru to spice up your next batch.

Let’s make some noise 🎺 (and bubbles!) together. I can’t wait to see what you’re fermenting.

Speaking of bubbles, if you're especially curious about kimchi—or want to dive deeper into its bold, flavorful world—I've got something exciting coming your way.

📢 Want to feel confident making kimchi? I'm putting together a short, hands-on Kimchi Masterclass—and I'm looking for a few enthusiastic students to be part of it from the very beginning as Founding Members.

If you'd love extra support, guidance, and all my best kimchi-making tips in one easy-to-follow place, this is for you.
