The Perfect Pie Crust Ratio
Flour : Fat : Water (by weight)
300g + 200g + 100g
Makes 2 perfect 9-inch pie crusts
The 3:2:1 Pie Crust Rule
Flour
300g (2½ cups)
All-purpose flour (structure)
Fat (Butter)
200g (14 tbsp)
Cold butter, cubed (flakiness)
Water
100g (7 tbsp)
Ice-cold water (binds dough)
Formula: Water × 2 = Fat | Water × 3 = Flour | Plus: ½ tsp salt per crust
Scaling Pie Crust Batches
| Batch Size | Flour (3 parts) | Butter (2 parts) | Water (1 part) | Salt | Yield |
|---|---|---|---|---|---|
| Single Crust | 150g (1¼ cups) | 100g (7 tbsp) | 50g (3 tbsp) | ¼ tsp | 1 crust (9") |
| Double Crust | 300g (2½ cups) | 200g (14 tbsp) | 100g (7 tbsp) | ½ tsp | 2 crusts (9") |
| Triple (Lattice Top) | 450g (3¾ cups) | 300g (1¼ cups) | 150g (10 tbsp) | ¾ tsp | 1 bottom + lattice |
| Mini Pies (6) | 225g (1¾ cups) | 150g (10 tbsp) | 75g (5 tbsp) | ⅓ tsp | 6 mini crusts (4") |
All-Butter vs Butter-Shortening Pie Crust
🧈 All-Butter Crust
Ratio: 3:2:1 (flour:butter:water)
300g flour + 200g cold butter + 100g ice water
Flavor: Rich, Buttery
Best flavor - tastes like butter! Golden color.
Texture: Very Flaky
Layers shatter when you cut. Tender, delicate.
Pros:
- • Superior flavor (butter tastes amazing)
- • Flakiest texture when done right
- • Natural ingredients (no processed fats)
Cons:
- • Harder to work with (butter melts fast)
- • Can shrink more during baking
- • Less forgiving for beginners
Best For:
Fruit pies, tarts, quiche, savory pies
🥧 Butter-Shortening (50/50)
Ratio: 3:2:1 (flour:fat mix:water)
300g flour + 100g butter + 100g shortening + 100g water
Flavor: Good (Less Buttery)
Butter adds flavor, shortening is neutral
Texture: Tender & Flaky
More tender (less shattering). Holds shape better.
Pros:
- • Easier to work with (shortening stable)
- • Less shrinkage during baking
- • More forgiving for beginners
- • Holds shape better (decorative edges)
Cons:
- • Less flavor than all-butter
- • Waxy mouthfeel if too much shortening
- • Not as flaky as all-butter
Best For:
Decorative pies, beginners, humid climates
Classic Flaky Pie Crust Recipe (2 crusts)
Ingredients (3:2:1 Ratio)
- All-purpose flour 300g (2½ cups)
- Unsalted butter (cold, cubed) 200g (14 tbsp)
- Ice-cold water 100g (7 tbsp)
- Salt ½ tsp
- Sugar (optional, for sweet pies) 1 tbsp
Instructions
- 1 Mix flour and salt. Add cold butter cubes. Cut in with pastry cutter until pea-sized pieces remain.
- 2 Add ice water 1 tbsp at a time. Mix with fork until dough just comes together (don't overwork!).
- 3 Divide dough in half. Shape into 2 disks. Wrap in plastic. Chill 1 hour minimum (or overnight).
- 4 Roll out on floured surface to 12" circle (⅛" thick). Transfer to 9" pie pan.
- 5 Trim edges, crimp as desired. For blind baking: line with parchment + pie weights, bake 375°F 20 min.
❄️ Why Ice Water & Cold Butter?
Cold fat creates steam pockets during baking = flaky layers. Warm butter melts into flour = tough, dense crust.
Why the 3:2:1 Ratio Works
🧈 High Fat Content (⅔ of flour weight)
The 2:3 fat-to-flour ratio creates tender, flaky texture. Fat coats flour = minimal gluten development = tender crust.
💧 Minimal Water (Just Enough to Bind)
Water activates gluten. Too much = tough crust. The 1:3 water-to-flour ratio provides just enough moisture to hold dough together.
🥮 Flaky Layers
Pea-sized butter pieces create steam pockets during baking. Steam pushes layers apart = flaky texture (like laminated dough, but easier).
📐 Easy to Scale
Start with water amount, double for fat, triple for flour. Simple multiplication!
Common Pie Crust Problems & Fixes
❌ Tough, Hard Crust
Causes: Overworked dough (too much gluten), too much water, not enough fat.
Fix: Mix just until dough comes together. Use 200g fat exactly (weigh it!). Handle dough minimally.
❌ Shrinks During Baking
Causes: Not chilled long enough, dough stretched (not rolled), overworked gluten.
Fix: Chill 1+ hours. Roll (don't stretch) dough. Let rest 30 min in pan before baking.
❌ Not Flaky, Dense Texture
Causes: Butter too warm (melted into flour), overmixed, butter pieces too small.
Fix: Use ice-cold butter. Keep butter pieces pea-sized (don't pulverize). Work fast, chill often.
❌ Dough Too Dry, Crumbly
Causes: Not enough water, flour measured incorrectly (too much).
Fix: Add water 1 tbsp at a time. Weigh flour (240g per 2 cups). Dough should barely hold together.
❌ Soggy Bottom
Causes: Wet filling, underbaked, too much filling.
Fix: Blind bake crust first. Bake on lower rack (bottom gets more heat). Use glass/metal pan (not ceramic).
❌ Burnt Edges Before Center Cooks
Causes: Oven too hot, edges exposed too long.
Fix: Use pie shield or foil around edges. Bake at 375°F (not 400°F). Shield edges after 20 min.
Pie Crust Techniques
Food Processor Method (Fastest)
- 1. Pulse flour + salt
- 2. Add cold butter, pulse 10-15 times (pea-sized)
- 3. Add ice water, pulse until just combined
- 4. Don't overprocess!
Pro: Fast, consistent. Con: Easy to overmix.
Pastry Cutter Method (Traditional)
- 1. Mix flour + salt in bowl
- 2. Add cold butter, cut with pastry cutter
- 3. Work until pea-sized pieces form
- 4. Add water, mix with fork
Pro: More control, traditional. Con: Takes longer, arm workout.
Frozen Butter + Grater Method
- 1. Freeze butter 30 min
- 2. Grate frozen butter into flour
- 3. Toss to coat, add water
- 4. Mix gently
Pro: Super flaky, easy. Con: Need box grater, hands get cold.
Fraisage Method (French)
- 1. Make dough as normal
- 2. Use heel of hand to smear dough
- 3. Push small amounts across work surface
- 4. Creates long butter streaks = extra flaky
Pro: Flakiest result. Con: Advanced technique, messy.
Blind Baking (Pre-Baking Empty Crust)
When to blind bake:
Full Blind Bake (Completely Cooked):
- • Cream pies, custard pies
- • No-bake fillings (key lime, chocolate silk)
- • Pies with cooked filling added later
Method: Line with parchment, fill with pie weights. Bake 375°F 20 min. Remove weights, bake 10 more min until golden.
Partial Blind Bake (Par-Baked):
- • Pumpkin pie, pecan pie
- • Quiche, savory tarts
- • Pies with wet fillings that bake long time
Method: Line with parchment, fill with weights. Bake 375°F 15 min. Remove weights. Add filling, finish baking per recipe.
Pro Tips for Perfect Pie Crust
⚖️ Weigh Ingredients for Best Results
300g flour is exact. "2½ cups" varies wildly. Weight = consistency. Invest in kitchen scale!
❄️ Keep Everything Cold
Butter, water, even flour can be chilled. Warm ingredients = melted butter = tough crust. Work in cold kitchen if possible.
⏰ Chill Dough 1+ Hours (Overnight Better)
Gluten relaxes = easier to roll, less shrinkage. Flour hydrates = more tender. Butter firms up = flakier layers.
🍚 Use Rice or Beans as Pie Weights
If no pie weights, use dried rice/beans. Line crust with parchment first. Reuse rice/beans indefinitely (don't cook/eat them!).
🥶 Freeze Shaped Crust Before Baking
After shaping in pan, freeze 15 min. Super-cold dough = minimal shrinkage, holds shape perfectly.
📏 Roll Between Parchment Sheets
Prevents sticking without extra flour (too much flour = tough crust). Easy to transfer to pie pan.
