Case File 1.5: The Return of the Bread Soup Curse
Mission Objective: Push the envelope. Can I increase stealth flour percentage while maintaining cover?
Stealth Level: 8% (ambitious)
The Formula:
- 294g puolikarkea vehnäjauho (reduced to make room)
- 26g oat flour (coffee-grinder pulverized)
- 200ml cellar juice
- 60ml lukewarm water
- 2 tbsp applesauce
- 1 tbsp rapeseed oil
- 1 tbsp tumma siirappi
- 1 tsp salt
- 2 tsp yeast
Method: Bread machine, Program 1 (Basic White), 750g setting, overnight timer.
Deployment: Morning reveal.
Target Response: N/A – Loss of structural integrity prevented standard deployment.
Assessment: Partial success. The loaf rose beautifully overnight, then collapsed into a crater during baking. The crust divorced itself from the crumb and hovered there like a sad roof over a sadder interior.

However.
The crumb inside? Soft, open, airy – exactly the texture I was going for. The middle slices were just… fun shaped. Sandwiches with character.

Taste test confirmed that it was fine. No oat detection. Stealth intact. Just a bit damper than 1.0 – noticeable but not the full soup situation from the Hawaiian Bread Disaster.
Lessons Learned: In Case File 1.0, I noted (and I quote myself here) that “increasing the stealth flour percentage may require liquid adjustments.”
I did not adjust the liquid.
I had planned to learn from my mistakes. Just, apparently, not until after I’d made them again. If you’re experiencing déjà vu, so am I. We’ve been here before. The bread was too wet, I was busy theorizing about gluten development and Finnish flour protein content, and the actual problem was staring me in the face the whole time.
Same curse, different loaf.
What I did learn was that oat flour absorbs liquid differently than wheat flour. I increased the oats but kept the liquid the same. At 5%, the dough could handle being borderline soup. At 8%, it couldn’t.
The fix wasn’t less oats. It was less liquid.
Status: Structural failure, but stealth remains viable at 8%. Recalibrating hydration for next attempt.

Next: Case File 1.6, in which I finally learn to measure.
