Preheat the oven to 450 degrees F and place the rack in the lowest position. Place a piece of plastic wrap (or foil) out on the counter. Flour the plastic wrap and place the pie crust dough on the floured work surface. Flour a rolling pin and roll one dough disk out into a large round circle approximately 12 inches across. Carefully lift the plastic wrap and flip the dough circle over into a 9-inch deep-dish pie pan. Gently fit the pie dough down into the pie pan—don't stretch it. Then fold the rough edges under and pinch-crimp the edges with your fingers.: The kitchen will fill with an anticipatory warmth as the oven climbs, and starting at a high temperature gives the pie crust an initial lift and flake. You should hear the faint hum of the oven stabilizing as it reaches temperature, and visually the heating element may glow before it settles. This early blast helps set the bottom crust so it absorbs less filling liquid. A frequent mistake is skipping the preheat which leads to a soggy bottom crust, so always wait until the oven reaches the proper temperature.
Place the lemon juice in a large bowl. Peel and thinly slice all the apples (1/8- to 1/4-inch thick) tossing in the lemon juice as you add them to the bowl.: When you flour the surface and roll the dough, you want a dusting that prevents sticking but does not dry the dough out. The soft, cool dough will feel tacky at first, and the gentle pressure of the rolling pin should spread it evenly. Rolling on plastic wrap also makes transferring the dough simpler, and you will notice less tearing when you pick it up. Avoid pressing too hard, as overworked dough loses its lightness and can become tough.
Add the Driscoll’s Raspberries, granulated sugar, raspberry preserves, corn starch, spices, and salt to the apples. Gently toss the mixture by hand to coat. Scoop the raspberry apple filling into the pie crust. Shake a little so the filling settles into place.: The flour creates a thin barrier so the dough slides instead of sticking, which makes achieving an even circle easier. As you move the rolling pin outward, the dough should unstick and shift smoothly; if it resists, dust a touch more flour. The dough will be slightly chill to the touch and should not feel greasy. Overflouring can dry the edges, so use the minimum needed to work comfortably.
Roll out the second pie crust and use a cookie cutter to cut fun shapes for the top crust. (I used a heart cookie cutter.) Lay the pie crust shapes over the filling, overlapping on the edges. Then whisk the egg and water to create an eggwash. Brush the eggwash over the top of the pie crust, then sprinkle the top of the crust with coarse Demerara sugar.: Rolling from the center outward produces an even thickness, and you will see faint flour lines blending into a uniform surface. The dough should have a consistent translucence when thin enough, but still hold its shape when lifted. If the edges crack, a quick dab of cold water smooths them. A common error is rolling too thin near the edges, which can tear during transfer, so aim for steady, even pressure.
Place the pie in the oven, and LOWER THE TEMPERATURE TO 375 DEGREES F. The extra heat from the beginning gives the crust a little head start in baking. Bake the pie for 70-80 minutes, until golden and bubbly. If the crust starts to get dark, loosely cover with foil while baking. *Make sure you see the juices bubbling – otherwise the filling will be runny.: The flip feels a little theatrical, and watching the dough drape into the pan is satisfying as it settles. Use the plastic wrap to support the dough, then gently ease it down so the bottom sits flat. If air pockets appear, press them out with your fingertips. Don’t stretch the dough while fitting it in, as stretched dough springs back while baking and can shrink awkwardly.
This is the hard part… DO NOT cut the pie until it has cooled down to room temperature. I know it smells amazing and is very hard to resist, but the filling needs time to settle and set, so it’s not soupy. If you cut your pie too soon, it will fall apart. I suggest making the pie in evening before you need it and let it rest overnight.: Press the dough into the corners and up the sides, coaxing it into place without tugging. The surface should be smooth and unstrained, with a neat seam where the edge meets the rim. Folding under the rough edges creates a thicker rim for crimping. If you stretch, the dough will pull away and create gaps that fill with juice, so take care to ease it in.
Then fold the rough edges under and pinch-crimp the edges with your fingers: Crimping seals the edge and gives the pie an attractive border. Use your thumb and forefinger to pinch consistent scallops or press with a fork for a simpler finish. The crust edge will feel firmer than the base, which is desirable for a sturdy rim. Overhandling the edge can warm the butter in the dough too much, reducing flakiness, so work quickly and return the pan to the fridge if needed.
Place the lemon juice in a large bowl: The bowl will be the staging area for the fruit, and the citrus will coat the apples to prevent browning while contributing a subtle lift. Pouring the lemon juice first makes it easy to add slices directly into an acidic bath. Avoid using bottled juices with added flavors, as they can alter the profile of the filling.
Peel and thinly slice all the apples one eighth to one quarter inch thick tossing in the lemon juice as you add them to the bowl: As you slice, the fresh scent of the apples releases, a crisp aroma that signals freshness. Thin, uniform slices cook evenly, softening without collapsing, and tossing them immediately in the lemon juice keeps color vibrant. A common slip is uneven slicing which leads to some pieces overcooking while others remain firm, so aim for consistency.
Add the Driscoll’s Raspberries granulated sugar raspberry preserves corn starch spices and salt to the apples: When you add the raspberries and sweeteners, the bowl fills with a bright fruity smell, and you can see the sugar begin to draw juice from the fruit. The addition of cornstarch is critical because it will thicken those juices during baking into a luscious, sliceable filling. Mix gently to avoid crushing the raspberries , as you want some texture in the final pie. Over mixing can turn everything into a uniform mush, so toss with care.
Gently toss the mixture by hand to coat: Using your hands gives you control and a tactile sense of how the mixture is coming together, feeling the weight of the fruit and the slight tackiness from the preserves. The goal is even distribution so every slice has both apple and raspberry notes. If you press too hard, the fragile berries will break down, leading to a less interesting texture.
Scoop the raspberry apple filling into the pie crust: As you transfer the filling, the pan will take on a colorful mound of fruit. Shake the pan a little so the filling settles into place and fills any gaps, leaving a small dome in the center which will sink slightly as it bakes. The visual cue you want is an even top with no large empty pockets. Overfilling can cause spillage, so leave a modest border for the top crust.
Roll out the second pie crust and use a cookie cutter to cut fun shapes for the top crust: Rolling the second disk evenly ensures your decorative shapes are consistent, and cutting shapes like hearts creates a charming top that vents while looking pretty. The shapes will brown and crisp, creating both form and function. If shapes are too thin they may burn, so aim for moderate thickness.
Lay the pie crust shapes over the filling overlapping on the edges: Layering the shapes creates an artisanal look and allows steam to escape while holding in most of the juices. As you arrange them, the contrast between the golden crust and the jewel toned filling becomes striking. Be mindful to overlap enough to seal the edges, but not so much that steam cannot vent properly.
Then whisk the egg and water to create an eggwash: The rhythmic motion of whisking produces a smooth glossy emulsion that will form a beautiful sheen on the crust. This wash enhances color and helps any sprinkling sugar adhere. If the wash pools, dab lightly with a brush to distribute it evenly and avoid soggy patches on the dough.
Brush the eggwash over the top of the pie crust then sprinkle the top of the crust with coarse Demerara sugar: As you brush the wash, the surface becomes glossy and ready to caramelize, and the coarse sugar adds texture and a delicate crackle once baked. The sugar's molasses notes deepen the crust flavor, making each bite more complex. Too much sugar can burn, so apply a modest sprinkle for the best balance.
Place the pie in the oven and lower the temperature to 375 degrees F: That initial high heat jump starts the crust, and lowering to 375 degrees F allows the filling to cook through without burning the top. You will notice the kitchen filling with a richer, spiced fruit aroma as juices begin to bubble. If the crust edges brown too quickly, tent loosely with foil to prevent overbrowning. A common oversight is leaving the pie too close to the top element, so ensure the rack remains in the lowest position.
Bake the pie for 70 to 80 minutes until golden and bubbly: During baking you should see active bubbling near the vents or edges, a sign the cornstarch is doing its job and the filling is thickening. The crust will turn a deep golden brown and the sugar will glint on top. If bubbling is absent, the filling may remain runny, so peek through the glass to confirm. If the crust starts to get dark, loosely cover with foil to prevent burning.
Make sure you see the juices bubbling otherwise the filling will be runny: The bubbling indicates proper thickening and that the interior reached a high enough temperature to activate the cornstarch . You will also smell a warm, cooked fruit sweetness that signals doneness. Cutting too soon is the main mistake, as it prevents the filling from setting and yields a sloppy slice.
This is the hard part do not cut the pie until it has cooled down to room temperature: Cooling lets the filling set into a sliceable consistency, and the aromas will become more settled and composed. If you slice while hot, the filling will flow and the structure collapses, so patience yields cleaner presentation. I recommend making the pie a few hours or even the evening before serving to give it ample time to rest.
I suggest making the pie in evening before you need it and let it rest overnight: Allowing the pie to rest overnight deepens the flavors and firms the filling for neater slices the next day. The crust remains pleasantly crisp and the fruit continues to meld, producing a more harmonious bite. The main caution is storing it uncovered too long in humid conditions, which can soften the crust, so tent lightly with foil if necessary.
