A little about this dish

Ingredients (for 8)

All-purpose flour — 2 1/2 cups
Sugar — 1 tbsp
Salt — 1 tsp
Unsalted butter — 1 cup (2 sticks), chilled and cut into cubes
Ice water — 1/2 cup
Apples (granny smith, honeycrisp, and pink lady) — 6 cups, sliced
Sugar — 1 cup
Cinnamon — 1 tsp
Nutmeg — 1/4 tsp
Allspice — 1/4 tsp
Salt — 1/2 tsp
Unsalted butter — 1/4 cup
All-purpose flour — 1/4 cup
Lemon juice — 1 tbsp
Egg — 1, beaten with 1 tbsp of water

Preparation

Step 1 — 🥣💼🧂

In a large bowl, mix flour, sugar, and salt. Add chilled butter and cut in with pastry blender or fingertips until the mixture forms pea-size pieces.
Step 2 — ❄️💧👋

Drizzle ice water over the mixture and mix until it forms a ball.
Step 3 — 🌬️🌡️🕰️

Divide the dough into two disks, wrap in plastic wrap, and refrigerate for at least 30 minutes.
Step 4 — 🍎🧂🥧

In a large bowl, mix sliced apples, sugar, cinnamon, nutmeg, allspice, and salt. Melt butter in a saucepan and mix in flour until smooth. Add butter mixture to the apple mixture along with lemon juice and toss to coat.
Step 5 — 🔄📏🥧

On a floured surface, roll out one dough disk into a 12-inch circle. Place it in a 9-inch pie dish, trimming the overhang to 1/2 inch. Roll out the other dough disk into a 12-inch square. Cut out the pi symbol in the center of the dough using a cookie cutter or knife.
Step 6 — 🥧🍎🎨

Pour the apple filling into the dough-lined pie dish. Place the pi cut-out on top of the filling. Cut remaining dough into strips and weave them in a lattice pattern on top of the filling. Brush with the egg wash and sprinkle with demerara sugar.
Step 7 — 👩‍🍳🔥👁️

Bake for 60-70 minutes at 375°F, until the crust is golden brown and the filling is bubbling. Cool before serving.

A final fox tip

To make it gluten-free, use a gluten-free flour mix. For a vegan version, substitute the butter with vegan butter and the egg wash with a non-dairy milk wash. Kids can help decorate the pie by cutting out the pi symbol and weaving the lattice pattern.
