What bakers say
“Arrived alive and doubled within four hours. Best loaf I've ever pulled out of my oven.”
“I emailed with a proofing question at 10pm. A reply from Maren by 8am. That is unheard of.”
“The dehydrated culture revived on day two. Six months in and my starter is still robust.”
Chapter I
One home kitchen, four starters, a hundred jars.
"Apron Maven began in 2018 with four distinct sourdough starters on a home-kitchen windowsill and a stubborn belief that home bakers deserve better than a packet of dry yeast."
Eight years later, we still fill every jar by hand, twice a day, from a small baking facility. Those four cultures have travelled, tested, and shipped with the same care we'd take pouring them for a friend.

From the kitchen
Recipes we bake weekly
No.01 · Sourdough
Simple Artisan Sourdough Loaf
A beginner-friendly artisan loaf with a crackling golden crust and open, airy crumb. No autolyse, no preferment — about 25 minutes of hands-on work spread over an overnight rise and a long cold proof.
Beginner · About 18 hours (25 minutes hands-on) + 45 minutes bake
No.02 · Pastry
Easy Homemade Baklava
Crisp, buttery, pistachio-packed baklava made with a forgiving homemade phyllo — no store-bought sheets and no special Turkish rolling pin. Yogurt and vinegar relax the dough so it rolls almost transparent.
Intermediate · 10 hours 35 minutes (about 2 hours hands-on)
No.03 · Bread
The Classic Country Loaf
A high-hydration boule with an open crumb and a deeply caramelized crust. Our workhorse loaf — the one we bake every week.
Intermediate · 24 hours (mostly hands-off)
No.04 · Flatbread
Overnight Sourdough Focaccia
Pillowy, dimpled, glossy with olive oil. A forgiving bake that turns leftover starter into a dinner-party centerpiece.
Beginner · 18 hours
No.05 · Bread
Traditional San Francisco Sourdough
The tangy, blistered loaf that made a city famous. This is the recipe we developed for our San Francisco starter.
Advanced · 30 hours
No.06 · Bread
Weekday Sourdough Sandwich Loaf
A soft, square-topped pan loaf enriched with a little butter and milk. Slices clean, toasts beautifully, and fits inside a lunchbox.
Beginner · 12 hours
No.07 · Discard
Sunday Discard Pancakes
The recipe that made us stop feeling guilty about throwing starter away. Tangy, tender, ready in 15 minutes.
Beginner · 15 minutes
No.08 · Discard
Griddled Sourdough English Muffins
All the nooks and crannies, none of the yeast packets. Cooked on the stovetop — no oven required.
Beginner · 16 hours
No.09 · Pizza
Weeknight Sourdough Pizza Dough
Mix Sunday night, bake pizzas Monday through Wednesday. A cold-ferment dough that only gets better with time.
Intermediate · 24–72 hours
No.10 · Sweet
Sourdough Brioche Cinnamon Rolls
An enriched, buttery brioche laminated with cinnamon sugar and glazed while warm. Start Saturday afternoon, eat Sunday morning.
Advanced · 20 hours
No.11 · Bread
Cranberry Walnut Batard
A holiday loaf that looks like a bakery centerpiece and tastes like something between dessert and dinner. Great with sharp cheese.
Intermediate · 26 hours
No.12 · Bread
Toasted Seed & Multigrain Boule
A hearty, tightly-crumbed boule loaded with toasted sunflower, pumpkin, sesame and flax. The one we bring to potlucks.
Intermediate · 28 hours
No.13 · Bread
Weekend Sourdough Baguettes
Thin, shattering crust; open, custard-y crumb. Baguettes are a two-day project — the shaping alone is worth the practice.
Advanced · 36 hours
No.14 · Bread
New York Style Sourdough Bagels
Boiled in barley malt, baked on parchment, chewy in the middle and glossy on top. A proper Sunday project.
Advanced · 20 hours
No.15 · Breakfast
Honey-Sweetened Sourdough Bagels
Chewy, golden rings with a whisper of honey in the dough and a quick boil before baking. Easier than a bakery run — and far more satisfying.
Intermediate · 14–16 hours (mostly overnight)
No.16 · Bread
Everyday Sourdough Sandwich Loaf
A soft, square-cornered pan loaf enriched with a little milk and butter. Slices thin without tearing — our house sandwich bread.
Beginner · 16 hours
No.17 · Breakfast
Griddle-Cooked Sourdough English Muffins

Beginner · 14 hours (mostly overnight)

Neapolitan-style dough with 24-hour flavor. Blistered leopard-spotted crust in a home oven, no fancy equipment required.
Intermediate · 24 hours
No.19 · Snack
Sourdough Discard Cheddar Crackers
Thin, crisp, obscenely cheesy. The best possible answer to 'what do I do with all this discard?'
Beginner · 1 hour + chill
No.20 · Snack
Sourdough Soft Pretzels
Deep-amber, chewy, salt-crusted. A quick alkaline bath gives them the signature snap without lye.
Intermediate · 18 hours
No.21 · Flatbread
Skillet Sourdough Tortillas
Soft, pliable, faintly tangy tortillas that stay flexible for days. A discard bake you'll come back to weekly.
Beginner · 3 hours
No.22 · Bread
Cheddar & Jalapeño Boule
Sharp cheddar in molten pockets, mellow pickled jalapeños threaded through the crumb. Ridiculous with a bowl of chili.
Intermediate · 24 hours
No.23 · Enriched
Sourdough Chocolate Babka
An enriched, laminated loaf twisted around a dark chocolate-cocoa filling. Inspired by King Arthur's babka but built on a slow overnight levain.
Advanced · 20 hours

Intermediate · 18 hours
No.25 · Whole grain

Dark, dense, and faintly sweet with molasses and cocoa. A classic deli loaf that slices thin for smoked fish and sharp cheeses.
Intermediate · 22 hours
No.26 · Discard

A King Arthur-inspired way to use up discard: dense, glossy-topped brownies with a subtle tang that balances the chocolate.
Beginner · 1 hour
No.27 · Discard

Beginner · 45 minutes
No.28 · Bread
Overnight Sourdough Ciabatta
High hydration, wildly open crumb, blistered crust. A slipper-shaped loaf that shines under olive oil or split for sandwiches.
Advanced · 20 hours
No.29 · Flatbread
Puffing Sourdough Pita
Soft, pocketed rounds baked on a screaming-hot stone. Great with hummus, or split and stuffed the next day.
Beginner · 16 hours
No.30 · Enriched
Cinnamon-Sugar Morning Buns
A laminated, muffin-tin cousin to the cinnamon roll. Crackly sugar edges, soft spiraled center. Inspired by the King Arthur bakery classic.
Advanced · 20 hours
