Moisture Treatment
EasyRehydrate the surface before baking.
- Mist dough surface lightly with water
- Let sit for 5 minutes
- Mist again if skin persists
- Score and bake immediately
Skin Forming
ProofingWhen dough develops a dry skin during proofing, it affects oven spring and creates an uneven crust. The skin cannot expand properly when steam hits it in the oven. Preventing and fixing this issue is straightforward.
Skin Forming in sourdough most often traces back to Skin forms when the dough surface loses moisture to the air faster than it can be replaced from within, a final proof-stage problem you can usually correct mid-bake. This page lists 3 immediate interventions to try on the current batch plus 4 adjustments to stop it recurring. Fixes assume a 68-72°F kitchen and an active, ripe starter.
How do I fix skin forming right now?
Work through these reversible steps on the batch in front of you, in order. Each one targets a different failure mode, so the first match is usually the fix — stop as soon as the dough responds and resume your normal process from there.
- 1Lightly mist the dough surface with water using a spray bottle
- 2Cover tightly with plastic wrap or a damp towel
- 3Score through any skin—the cut will open during baking
What are the detailed fixes for skin forming?
If the quick steps above did not resolve things, these deeper adjustments rework the mix, fermentation, or handling stage where skin forming usually originates. Each card explains what to change, the reason it works, and the baking stage it belongs to.
Oil Application
EasyApply oil to prevent further drying.
- Brush surface lightly with olive oil
- This softens existing skin
- Cover tightly for remaining proof
- Score through oiled surface
What causes skin forming in sourdough?
Skin forms when the dough surface loses moisture to the air faster than it can be replaced from within. Contributing factors include: Proofing uncovered or poorly covered, Low humidity environment, Air conditioning or heating removing moisture, Proofing too long without cover, Using a cloth cover instead of plastic.
How do I prevent skin forming next time?
Prevention is easier than a mid-bake rescue. The tips below target the variables — starter timing, hydration, temperature, and handling — that most often set up skin forming, so you build the fix into your process instead of reacting to a dough that has already drifted.
- Always cover proofing dough tightly with plastic wrap or a lid
- Use a banneton with a shower cap cover for easy sealing
- Oil the plastic wrap to prevent sticking and seal moisture
- In dry environments, proof in a closed container or proof box
