Free Willy 2’s First Loaf — Our Whole Wheat Sourdough Story
Free Willy 2 first loaf is done, and I am not being dramatic when I say it turned out better than I expected. This is the same recipe we have been using all along — the Baked Collective 100% whole wheat sourdough, four ingredients, no shortcuts — but this time instead of shaping it into a boule, I put it into a loaf pan. Because Jason needs actual sandwich bread for his Mediterranean diet, and you cannot really make a sandwich with a round loaf. Free Willy 2 delivered.

We have been on this whole wheat sourdough journey with Free Willy 2 for a while now. He started as an all-purpose starter that I slowly converted over to whole wheat — feeding by feeding, week by week — specifically so I could make Jason a bread that fits his Mediterranean diet. Whole wheat, real ingredients, nothing processed. The first two bakes were boules, which were beautiful and delicious but not exactly what you slice for a sandwich. This time I used a loaf pan, and the result is exactly what we were working toward.
The recipe is still the same four ingredients — 100g active whole wheat sourdough starter, 500g whole wheat flour, 375g water, 10g salt. Six stretch and fold rounds, overnight cold proof, baked the next morning. I use King Arthur 100% Whole Wheat Flour for Free Willy 2 — it is milled from 100% hard wheat and gives this bread that robust, nutty flavor that makes it worth baking. The only difference from the previous bakes is the shaping. Instead of pulling the dough into a tight boule and scoring it, I shaped it into a log, set it into my Wilton Gold Premium Non-Stick Loaf Pan , and let the oven do its thing. The oven spring was real. The crust came out dark and crackling. And when I squeezed a slice, it sprang right back. That spring-back is what you are looking for — it means the crumb is open, the fermentation did its job, and the Free Willy 2 first loaf is exactly what it needed to be.
This bread is for Jason. He has been patient through every feeding, every bake, every iteration of this starter. He never complained about the boules. But I know what he actually needs is something he can slice, load up with hummus and vegetables, and take for lunch. Free Willy 2 finally made that bread. I think we are going to be doing this one on repeat.

Free Willy 2 First Loaf FAQ — Your Whole Wheat Sourdough Questions Answered
Can I use a loaf pan instead of a Dutch oven for sourdough?
Yes — and that is exactly what I did with the Free Willy 2 first loaf. A loaf pan gives you that classic sandwich bread shape, which is far more practical for slicing and everyday use. You do not get quite the same crackling crust as a Dutch oven boule, but the crumb structure is just as good and the result is a bread you can actually build a meal around. For a whole wheat sourdough that is meant to be eaten every day, the loaf pan is the right call.
How do I know when my sourdough starter is ready to bake with?
Your starter needs to be at peak activity — doubled in size, domed on top, and full of bubbles. The classic float test works: drop a small spoonful in water and if it floats, you are ready. For Free Willy 2, peak usually happens around 5 hours after a baking feed at room temperature. If it is not doubling, it needs more time or more frequent feedings before bake day.
What is the spring-back test for sourdough bread?
The spring-back test is the simplest way to check if your loaf is done. Press gently on the top of the loaf — if it springs back immediately, the crumb has set and the bread is ready. If your finger leaves an indent that stays, the bread needs more time in the oven. The Free Willy 2 first loaf passed with flying colors. That spring-back is what tells you the fermentation did its job.
Why do you use whole wheat flour for this sourdough?
Jason is on a Mediterranean diet, which favors whole grains over refined flour. Whole wheat sourdough fits perfectly — the long fermentation process makes the nutrients more bioavailable and the flavor more complex than a standard whole wheat loaf. Free Willy 2 was converted from an all-purpose starter to whole wheat specifically for this purpose, feeding by feeding over several weeks. I use King Arthur 100% Whole Wheat Flour — milled from 100% hard wheat with that classic robust flavor.
How long should I wait before slicing a sourdough loaf?
At least one hour — and honestly longer is better. The crumb is still setting as the loaf cools. If you cut into it too soon, the interior will be gummy and dense even if the outside looks perfect. I waited about ten hours before slicing the Free Willy 2 first loaf, which felt like forever, but the crumb was exactly what it should be. Patience is the hardest ingredient in sourdough baking.
