One Jar at a Time
A Practical Fermentation Handbook

by Kelsey Bye
Fermentation doesn’t have to be complicated.
With endless recipes, techniques, starter cultures, and equipment, learning to ferment can quickly feel overwhelming. One Jar at a Time takes a simpler approach.
This practical handbook focuses on a handful of foundational ferments and the principles behind them, giving beginners the confidence to understand how fermentation works — and actually start fermenting.
Inside you’ll find:
• approachable, foundational recipes
• simple ingredients and accessible techniques
• clear explanations of the microbes doing the work
• repeatable methods for salt, alcoholic, and vinegar fermentation
• guidance for safely experimenting with your own variations
You don’t need a laboratory or a refrigerator full of starter cultures.
You need a jar, a few ingredients, and a little patience.
You don’t have to learn everything at once.
Just start — one jar at a time.
