Wash the bell peppers and roast them whole until the skins blister and char, in the oven, on the grill, or on the stovetop in a cast iron pan, turning as each side blackens.

Let the peppers rest a few minutes, then peel off the charred skin, cut each pepper in half, and remove the seeds and stems.

Spread the bread slices and walnuts on a sheet pan and toast in a 350°F (180°C) oven for 10 minutes, until the bread is dry and golden and the walnuts are fragrant.

Break the toasted bread into pieces and pulse it with the walnuts in a food processor until they form a coarse paste.

Add the roasted peppers, the garlic, and the hot chili (if using) and pulse until combined.

Add the salt, Aleppo pepper, paprika, cumin, and pomegranate molasses. Drizzle in the olive oil while pulsing until you reach your desired consistency, smooth or rustic.

Taste and adjust the seasoning: more molasses for brightness, salt for depth, or a spoonful of breadcrumbs if the dip is too loose.

Transfer to a container, cover, and refrigerate for 24 hours before serving to allow the flavors to develop.

To serve, spread into a shallow bowl, drizzle with olive oil and pomegranate molasses, and scatter pomegranate seeds over the top.
