Grandma’s Secret Cream of Tartar Pie Crust: Flaky & Irresistible

I still remember the first time I sneaked a peek at Grandma’s secret pie crust recipe tucked in her old recipe box. There it was—cream of tartar, scribbled in her looping handwriting with a little star next to it. "That’s the magic," she’d whisper, winking as she rolled out the flakiest, most tender crust you’ve ever tasted. It wasn’t just for show—that pinch of cream of tartar works like a charm, lifting the layers and giving the crust that melt-in-your-mouth texture you’ll dream about.

Decades later, I still make it exactly her way. No fancy tricks, just cold shortening, a splash of vinegar, and that secret ingredient hiding in the back of your spice cabinet. Whether it’s cradling a juicy peach filling or holding up a savory chicken pot pie, this crust never lets me down. And trust me, once you try it, you’ll never go back to store-bought again.

Ingredients for Grandma’s Secret Cream of Tartar Pie Crust

Gather these simple ingredients—the magic happens in the details:

• 3 cups all-purpose flour (about 12 oz): Spoon it lightly into your measuring cup and level it off. No packing!
• ¼ teaspoon cream of tartar: The secret weapon hiding in your spice rack.
• 1 teaspoon salt: Just enough to make the flavors pop.
• 1½ cups Crisco shortening: Straight from the fridge—cold is key! (Or use lard for extra flakiness if you’re feeling fancy.)
• 4–8 tablespoon very cold water: I keep mine in the freezer for 10 minutes first.
• 1 large egg, well beaten: Room temp is fine—we’re not monsters.
• 1 tablespoon white vinegar: Sounds weird, but trust Grandma on this one.

Pro tip: Measure everything before you start. Cold ingredients wait for no one!

Equipment You’ll Need for Grandma’s Secret Cream of Tartar Pie Crust

You don’t need fancy gadgets—just these trusty basics:

• Large mixing bowl: Big enough to really get your hands in there.
• Pastry cutter: Or two forks if you’re feeling old-school.
• Rolling pin: Grandma used a washed wine bottle in a pinch!
• Plastic wrap: For tucking that dough in like a blanket.

Bonus if you’ve got a food processor—it’ll save your arms some work, but hands work just fine too.

How to Make Grandma’s Secret Cream of Tartar Pie Crust

Follow these steps exactly like Grandma did—no shortcuts! The key is keeping everything cold and handling the dough like it’s a delicate treasure. (Which it is.)

Step 1: Mix Dry Ingredients

Grab your biggest bowl and whisk together the flour, cream of tartar, and salt until they’re best friends. No lumps allowed! I like to sift mine through my fingers like Grandma taught me—it’s oddly satisfying and makes sure everything’s evenly distributed.

Step 2: Cut in Shortening

Now for the fun part! Drop in those cold shortening chunks and start cutting them in with your pastry cutter. You’re aiming for pea-sized crumbs—some bigger flakes are totally fine. Pro tip: If your hands start warming the dough, walk away for 5 minutes. Cold = flaky. Warm = tough.

Step 3: Add Wet Ingredients

Make a little well in the center and pour in the beaten egg and vinegar. Use a fork to gently mix—just enough to incorporate. The dough will look shaggy and weird at this point. That’s perfect! The vinegar’s working its magic to keep things tender.

Step 4: Bind with Cold Water

Here’s where patience pays off. Sprinkle in the ice-cold water 1 tablespoon at a time, mixing lightly after each addition. Stop the second the dough starts clumping together when you squeeze it. Too wet? Add a pinch of flour. Too dry? One more teaspoon of water. You’ll know it’s right when it holds together but isn’t sticky.

Step 5: Chill and Roll

Divide the dough into two equal blobs (technical term), flatten into disks, and wrap them snugly in plastic. Now walk away for at least 30 minutes—this lets the gluten relax and the fat firm back up. Want extra flaky layers? Chill overnight. When you’re ready to roll, dust your surface lightly and go for it!

See? Not scary at all. Just remember: cold, quick, and gentle wins the flaky crust race every time.

Tips for Perfect Grandma’s Secret Cream of Tartar Pie Crust

Want to nail this crust like Grandma did? Here are my tried-and-true tricks:

• Chill everything: I even stick my flour in the freezer for 15 minutes first. Warm dough = sad, tough crust.
• Work fast: Handle that dough like it’s a hot potato—the less you touch it, the flakier it’ll be.
• Roll between parchment: No sticking disasters, and easy cleanup! Bonus: flip it straight into the pie dish.
• Patch with cold water: Got a tear? Dab a wet finger—it’ll melt together when baked.

Oh, and breathe! Even imperfect crust tastes amazing.

Variations for Grandma’s Secret Cream of Tartar Pie Crust

Once you've mastered Grandma's classic version, try these fun twists—she’d approve!

• Butter lovers: Swap half the shortening for cold butter cubes. Less flaky, but oh that flavor!
• Whole wheat boost: Replace 1 cup flour with whole wheat for nutty depth (great with pumpkin pie).
• Savory spin: Mix in 1 tablespoon rosemary or thyme when making pot pie crusts.

My favorite? A sprinkle of cinnamon sugar on apple pie crust edges before baking—Grandma’s "secret" second secret.

Storing and Freezing Grandma’s Secret Cream of Tartar Pie Crust

Good news—this dough freezes like a dream! Wrap those chilled disks tightly in plastic, then tuck them in a freezer bag for up to 3 months. Need it sooner? Fridge keeps it happy for 2 days. Just thaw overnight in the fridge before rolling—no shortcuts here, or you’ll fight sticky dough. (Voice of experience!)

Frequently Asked Questions About Grandma’s Secret Cream of Tartar Pie Crust

Got questions? I’ve got answers—straight from Grandma’s playbook:

Can I use butter instead of shortening?
Absolutely! Swap half the shortening for cold, cubed butter if you want richer flavor. Just know it won’t be quite as flaky—butter has water that creates steam pockets differently. (Grandma would shrug and say "Tastes good either way!")

Why vinegar? That seems weird!
Trust me, I thought so too! The acid relaxes the gluten so the crust stays tender instead of tough. And no—you won’t taste it. It’s like a tiny kitchen superhero.

Help! My dough’s too sticky—what now?
Sprinkle a teaspoon of flour over it, fold gently, and chill for 15 minutes. Sticky usually means it got too warm. (Grandma’s fix: "Cold hands, cold dough—problem solved.")

Can I skip the chilling step?
Don’t even think about it! That chill time lets the gluten relax and the fat firm up. Rushing = tough crust. Patience = flaky layers worth bragging about.
