Doughs & batters
Filo
φύλλο · An unleavened, paper-thin dough of Middle Eastern and Greek origin, traditionally hand-stretched (or rolled) to translucency and layered with fat to produce shatteringly crisp, flaky pastries when baked.
The formula
2:1 flour:water by weight + pinch salt + oil + optional vinegar/acid
Gourmet Traveller's canonical ratio is 2 parts flour to 1 part water by weight; a roughly equivalent volume measure is ~1 cup flour to ~⅓ cup water, with 1 tbsp oil and a pinch of salt per cup of flour. Optional vinegar (red wine, balsamic, or ouzo) tenderizes the gluten.
Identity
- Unleavened — no yeast, baking powder, or chemical leavener
- Stretched or rolled to translucency, not laminated with butter blocks
- Layered with oil or melted butter between sheets to crisp
- Name comes from Greek φύλλο meaning 'leaf', describing its paper-thinness
- Bakes shatteringly crisp and flaky, never airy/puffed
- Traditionally Greek, also foundational across Ottoman and Balkan cuisines
Ingredients
| Base | all-purpose flour (or a mix of whole wheat and all-purpose) | Provides the gluten structure that allows the dough to stretch without tearing; high-protein flour gives more elasticity. |
| Liquid | water | Hydrates the gluten; some regional recipes swap part of the water for yogurt or beaten egg. |
| Seasoning | salt | Tightens the gluten and seasons the finished pastry; dissolved in the water before mixing for even distribution. |
| Fat | olive oil (or neutral oil) | Adds tenderness and pliability and is brushed between layers; Kochilas uses ½ cup olive oil per ~4 cups flour, Gourmet Traveller treats it as optional. |
| Acid | red wine vinegar, balsamic vinegar, or ouzo | Acidic tenderizer that relaxes the gluten so sheets stretch thinner without snapping; Kochilas' recipe uses 1 tbsp per ~4 cups flour. |
| Enrichment | plain yogurt | Ionian regional variant; replaces part of the water, adds tang and tenderness. |
| Binder | egg | Epirote regional variant; replaces part of the water, adds richness and slight color. |
Method
- 1Combine flour and salt in a bowl or stand mixer; add water, oil, and any optional acid/yogurt/egg.Dissolving the salt in the water distributes seasoning evenly and prevents the dough from seizing; the fat and acid coat gluten strands to limit toughening.
- 2Knead 8–10 minutes (stand mixer) or 10–15 minutes by hand until the dough is soft, pliant, and smooth but not sticky.Sufficient kneading develops just enough gluten to make the dough elastic enough to stretch paper-thin without tearing.
- 3Shape into a ball, coat lightly with oil, cover, and rest at room temperature 30 minutes or up to several hours (Serious Eats / The Spruce Eats call for an extended rest).Resting relaxes the gluten network so the dough can be stretched thin; oil coating prevents a skin from forming.
- 4Divide rested dough into smaller balls (golf- to tennis-ball size), keep covered, and roll each into a thin round.Smaller portions are easier to handle and prevent premature drying of unworked dough.
- 5Stretch each round by hand over a floured surface (or drape over the back of the hand) until translucent — light should pass through.Hand-stretching is the traditional Greek technique that achieves the leaf-thin translucency impossible with a rolling pin alone.
- 6Layer the finished sheets between lightly oiled parchment or a floured cloth, brushing with oil or melted butter as you stack, then use in assembled pastries or cut and bake as needed.Oil between layers is what produces the characteristic crisp, flaky separation when baked — the dough itself contains no fat layers.
Techniques that matter
Hand-stretching over the knuckles
Allows the dough to be drawn out uniformly translucent without tearing, which a rolling pin cannot achieve.
Punch-kneading (Epirote)
Pressing the dough with the back of the fist while sprinkling in water develops gluten with less stickiness than conventional kneading.
Resting under an oiled cover
Relaxes gluten and keeps the surface pliable; an oiled surface prevents a dry skin that would crack on stretching.
Variations & derivatives
Ionian filoIonian Islands (Greece)
Reduce water by ~⅓ and add ½ cup strained plain yogurt with the liquids; produces a slightly richer, tangier dough.
Epirote filoEpirus (Greece)
Reduce water to ~1¼ cups per 4 cups flour and add one beaten egg; dough is mixed by the punch-knead technique in a flour well.
Whole-wheat filoModern Greek home kitchens
Kochilas blends 3 cups whole wheat with 1 cup all-purpose for a nuttier, more rustic sheet.
Minimalist flour-and-water filoGreek villages / traditional bakers
Some traditional recipes use only flour, water, and a pinch of salt — oil and acid omitted entirely.

Substitutions
- extra-virgin olive oil → neutral oil (sunflower, grapeseed) or melted butter — Neutral oil gives a cleaner flavor; melted butter adds dairy richness but can brown faster.
- red wine or balsamic vinegar → ouzo, lemon juice, or omit — Any mild acid tenderizes gluten; ouzo also adds anise aroma typical of Greek pastries.
- all-purpose flour → whole wheat flour (100%) or 50/50 blend — Pure whole wheat is less elastic and tears more easily; a 50/50 blend with all-purpose is safer.changes result
- yogurt (Ionian variant) → omit and add equivalent water — Yogurt adds tang and tenderness; plain water works but the result is less rich.
Troubleshooting
Dough springs back or snaps when stretched
Gluten not sufficiently rested or under-kneaded; too little hydration. → Cover and rest an additional 30–60 minutes; if still tight, work in a few drops of water and re-knead briefly.
Sheets tear during stretching
Dough too dry, over-floured during rolling, or stretched too quickly. → Brush surface lightly with water or oil, rest 10 minutes, and stretch more gradually; patch small tears by overlapping sheets — the layering hides them.
Dough is sticky and hard to roll out
Too much water, under-kneaded, or warm kitchen. → Dust surface and dough with flour sparingly and chill 15–20 minutes; if sticky throughout, knead in flour 1 tsp at a time.
Baked pastry is tough rather than crisp and flaky
Insufficient oil/butter between layers or sheets stretched too thick. → Brush every 2–3 sheets generously with melted butter or oil and aim for sheets thin enough that you can read print through them.
