Place an 18 x 12-inch (46 x 30 cm) serving board or platter on a clean, dry surface. Set the medium serving bowl near the center and arrange the 4 small bowls around it, leaving enough space for the apple wedges. The bowls should sit securely without crowding the edges of the board. This takes about 2 minutes.

Spoon 1 cup (about 300 g) of thick, room-temperature caramel apple dip into the medium serving bowl. Smooth the surface with a spoon so it's easy to dip into. The caramel should look glossy and thick enough to cling to a spoon rather than run off like a thin sauce. Allow about 1 minute.

Place 1/3 cup (about 60 g) mini semisweet chocolate chips into one small bowl and 1/2 cup (about 25 g) mini marshmallows into another. Keep them in separate bowls so guests can choose their favorites. Both toppings should be dry and loosely arranged, not packed tightly. Allow about 2 minutes.

Place 1/2 cup (about 55 g) finely chopped pecans into the third small bowl and 1 cup (about 40 g) mini pretzel twists into the fourth. Leave some pretzels whole and roughly break others to make them easier to sprinkle. The pecans should be in small, even pieces, and the pretzels should remain crisp. Allow about 2 minutes.

If the apples aren't already sliced, use the knife and cutting board to core and cut the 2 Honeycrisp apples (about 400 g total) and 2 Granny Smith apples (about 400 g total) into wedges about 1/4 inch (6 mm) thick. Keep the skins on for color and texture. The wedges should be firm, evenly sized, and easy to pick up. Allow about 5 minutes.

Transfer the apple wedges to the medium mixing bowl and drizzle with 1 tablespoon (15 mL) freshly squeezed lemon juice. Toss gently for about 30 seconds until the cut surfaces are lightly coated. Pat away excess moisture with paper towels so the caramel will stick more easily. The apples should look fresh and lightly glossy, not wet.

Fan the Honeycrisp and Granny Smith wedges around the serving bowls, alternating the varieties to create a colorful pattern. Keep the apple slices in overlapping rows so guests can pick them up easily. The board should look full, with the red, yellow, and green apple skins visible around the toppings. Allow about 5 minutes.

Adjust the bowls and apple wedges to fill any large gaps, keeping the caramel dip easy to reach. Place small serving spoons beside the toppings and caramel. Serve immediately while the apples are crisp and the pretzels are crunchy. Allow about 2 minutes for the final arrangement.
