About Ana — Food Engineer & Busy Mum
Hi, I'm Ana. Based in the Netherlands and trained as a food engineer, I realized after becoming a mum that most online sourdough advice is built for commercial bakeries—not real family kitchens.
When I started baking for my family, I fell deeply in love with clean, long-fermented sourdough at home. I cared about simple ingredients and natural digestibility—but I didn't have 14 uninterrupted hours to hover over a mixing bowl between naps, errands, and family life.
After years of testing, failed loaves, and applying food-technology principles to home fermentation, I stripped artisan sourdough down to the steps that actually matter: just 15 minutes of active hands-on time in a normal home kitchen, guided by dough temperature, aliquot rise percentage, and starch science rather than rigid clock schedules.
"Nobody tells you this when you start: sourdough isn't just a recipe you measure—it's fermentation science guided by nature. Once you understand the why behind temperature and gluten tension, the dough fits around your family's day instead of running it."
Food-Tech Precision
Trained in food engineering & fermentation kinetics—no mystical rules or guesswork.
15-Min Busy-Mum Workflow
Built in a real home kitchen for busy family schedules—4 ingredients and overnight fridge retards.
Zero-Waste Kitchen
One active starter powers weekend country loaves, weekday seeded bagels, and sweet bakes.
Fermentation Science, Simplified
Why My "Busy-Mum Food Engineer" Method Works
Most beginners fail because recipes give rigid clock times ("bulk ferment for 4 hours") instead of teaching you how to read your dough temperature and volume rise.
01
02
Let the Basket & Fridge Do the Work
Three quick coil folds build gluten tension, then a 12–16 hour overnight cold retard at 4°C locks in blistered crust, lactic-acetic balance, and effortless scoring.
03
The 3 Signs of a Perfect Bake
Steam-trapped oven spring in the first 20 minutes, deep Maillard caramelization, a 96–98°C core, and the classic hollow knock on the bottom crust.
04
One Starter, Endless Bakes
Once your starter is active, branch into seeded country boules, 60-second boiled sourdough bagels, blueberry-lemon loaves, and zero-waste discard treats.
