Weekend baker: how to keep a sourdough starter alive when you only bake once a week

A lot of would-be bakers quit because they think keeping a starter means feeding a needy pet twice a day forever. It doesn't. Daily feeding is what you do for a week or two while building a brand-new starter, or if you keep it on the counter by choice. Once a starter is established, the fridge turns it into a once-a-week, five-minute commitment. If your life is busy and you bake on weekends, you are the exact person the fridge method was made for.

Here is the whole thing as a week. The only "active" days are Friday and Saturday; the rest is the fridge doing the work for you:

Sometimes one Friday feed isn't enough, especially in a cold kitchen or after a longer-than-usual fridge stay. That's not failure, it's just a starter that needs one more wake-up feed. The reliable rule from the full fridge revival routine is to judge a fridge starter by its second or third feed, not its first. If Saturday morning looks flat, give it a feed and bake in the afternoon or evening instead, or push the bake to Sunday. The starter is fine; it just wanted a little more runway.

Life happens and you miss a weekend, or a few. An established starter handles a few weeks in the fridge between feeds without drama; it just gets more sour and will want two or three wake-up feeds instead of one when you come back. If you know you'll be away longer, a stiffer starter or simply drying a backup buys you months of insurance. The thing almost no beginner believes until they've seen it: a forgotten fridge starter is far more likely to be revivable than dead.

The one genuinely hard part of the weekend rhythm is remembering to feed on Friday night, because there's no daily habit to lean on; a once-a-week task is exactly the kind your brain drops. This is where a state-aware reminder earns its keep. Sourdough Tracker knows whether your starter is sleeping in the fridge or awake on the counter, and nudges you on the right day, so the Friday wake-up feed actually happens and Saturday's bake isn't a gamble. It keeps your whole weekly thread in one journal, so even after a skipped week you can see exactly where you left off. A once-a-week starter lives or dies on that one reminder landing.
