About

Ferment

Read full description

Ferment helps you make real sour pickles, sauerkraut, and kimchi at home. No vinegar, no canning, no special gear. Just vegetables, salt, and time. Whether this is your first jar or your fifth, the app stays in your pocket to answer the questions that come up along the way. These are naturally fermented foods. You salt the vegetables, keep them under the brine, and let them sour on the counter for a week or two. The result is crunchy, tangy, and alive. Ferment walks you through it and keeps you company the whole time. Ask the helper anything (new) The biggest part of this update. When a question comes up, just ask. Type it out, snap a photo of your jar, or leave a quick voice note, and you get a clear, plain answer back in seconds. Is this white film okay? Why did my kraut go soft? What can I make with this cabbage? It knows fermentation, it can read your photo, and it can help you build a simple recipe you can start tracking with one tap. Included with Premium. Get your salt right Salt is the one thing that really matters, and the math trips everyone up. The calculator does it for you. Use dry salt for shredded vegetables like cabbage, or a brine for whole vegetables like cucumbers. It handles different salt types and jar sizes, so you measure once and move on. Know what you are looking at See a cloudy brine, soft vegetables, or a film on top and not sure what it means? The visual guide walks you through what you are seeing, with reference photos for the common ones, and gives you a plain verdict: this is fine, do this, or start over. Most of what looks alarming is completely normal, and now you will know. Track your jars Keep an eye on up to 10 batches at once. Each one shows where it is in the process and what to expect next, with gentle reminders to press the vegetables back under the brine and to taste along the way. Log your notes, rate the sourness and crunch, and tap to make a good batch again. Recipes to start from One solid, tested recipe per type, written to actually work the first time. Sauerkraut, kimchi, garlic dill pickles from half-sour to full-sour, curtido, hot sauce, fermented carrots, and more. Each one points out what to watch for, and you can start a batch with reminders in a single tap. Straight answers on safety Plain, honest answers to the questions everyone has. Why salted vegetable ferments are safe to make at home, and how to trust your own eyes, nose, and taste. A quick per-batch checklist means you never have to second-guess. Made for everyday cooks You do not need to be an expert or know any of the lingo. If you have ever wanted to make your own pickles and were not sure where to start, this is for you. Calm, friendly guidance from someone who has made a few jars, not a textbook. 7-day free trial. Then $29.99/year or $4.99/month.
