Baking in Riverside: citrus groves, the Mission Inn, and warm, dry air

Riverside carries its food history out in the open. This is the birthplace of California's citrus industry, a story kept alive at California Citrus State Historic Park, where working groves and rows of fruit trees show what made this valley famous, and at the Parent Navel Orange Tree, the landmark tree from which California's Washington navel orange groves grew. Downtown, the Mission Inn Hotel & Spa — a sprawling National Historic Landmark built in Mission Revival style, full of courtyards, towers, and tiled corners — anchors a walkable center that feels unlike anywhere else in the Inland Empire. Just west of downtown, Mount Rubidoux rises above the Santa Ana River, its paved trail climbing to wide views over the valley floor. It is a city that understands growing things patiently, and sourdough fits right into that rhythm.

There is a practical side to baking here, too. Riverside kitchens tend to be warm, and the air is often dry — a combination that changes how dough behaves. Warmth speeds fermentation, so a starter can double faster and a dough can proof sooner than a recipe's timing suggests. Judge readiness by volume, bubbles, and feel rather than by the clock alone. Dry air pulls moisture from exposed dough, so keep your starter container covered, cover your bowl during the rise, and do not be surprised if a loaf needs a touch more water to reach a smooth, supple texture. Keep your waking starter in a comfortably cool corner away from direct sun and warm appliances, and it will settle into a steady, predictable rhythm that suits Riverside homes well.

How waking up your flakes actually works

Activation is simple, and that is the point. Stir the flakes into flour and water in a clean container, cover it, and let the culture start feeding. At each feeding, discard a portion and replace it with fresh flour and water. That rhythm keeps the good microbes fed and balanced instead of hungry and harsh, and within days you should see the signs bakers look for: bubbles through the mixture, a pleasant tangy aroma, and a rise that climbs reliably after each feed.

Once your starter doubles predictably and smells pleasantly tangy rather than sharp, it is ready to leaven dough. From there you choose the routine that matches how you bake. Feed it regularly on the counter if you bake often, or rest it in the fridge between bakes and refresh it before the next loaf. The included instructions walk through both paths in plain language, and the Academy goes deeper on feeding ratios, timing, and troubleshooting if you want to learn as you go.

Thinking about flavor? A proven culture gives you a dependable base for experimenting. Try a plain crusty loaf first to learn your starter's pace, then explore a citrus-kissed loaf inspired by Riverside's groves — a little orange zest folded into the dough brings brightness without overpowering the gentle tang. The everyday lesson is the same everywhere: a culture that already knows how to rise removes the hardest uncertainty.

What to bake first in your Riverside kitchen

Start simple and learn your culture on a straightforward loaf. Watch how it rises in your warm kitchen, how the crust colors, and how the crumb opens. That one bake teaches you more than any timetable. Next, branch out in the directions Riverside tables love: soft sandwich slices for packed lunches, bubbly pizza bases for family nights, olive-oil focaccia for sharing, and discard pancakes, crackers, and muffins so nothing from a feeding goes to waste.

If a loaf comes out dense or pale, do not assume the culture failed. The usual culprits are a dough pulled too soon, a starter used long after its peak, or a bowl left uncovered in dry air — all fixable on the next attempt. Change one thing at a time, note how long the rise actually took, and keep the feeding rhythm steady. That small habit is how a good first loaf becomes bread you can count on, loaf after loaf.

Frequently asked questions

Does Squirrelly Girl ship free to Riverside, California?

Yes. Shipping is free to Riverside and to addresses in all 50 states. Your starter arrives as shelf-stable flakes, so it travels well and can wait in the pantry until you are ready to activate it.

Will Riverside's warm, dry air affect my starter?

It can speed things up in a helpful way. Warmth encourages a faster rise, so watch for bubbles and doubling rather than following a fixed clock, keep containers covered so surfaces do not dry out, and store your waking starter in a comfortably cool spot.

What flour should I use for feedings and my first loaf?

Regular unbleached all-purpose or bread flour works well for both. Feed with the flour you bake with most often, keep the ratio consistent, and your culture will reward you with a steady rise and balanced flavor.

What happens if my starter does not activate?

That is covered by the guarantee. Follow the instructions, and if your flakes do not wake up as described, reach out and we will make it right — the details are on our Activation Guarantee page.
