Start by slicing the three ripe avocados in half and removing the pits. In a mixing bowl, mash the flesh until smooth, leaving some small chunks for texture.

Squeeze the juice of one lime directly into the mashed avocados. Mix well to prevent browning.

Fold in the finely chopped red onion, diced tomatoes, minced jalapeño, and fresh cilantro into the avocado mixture.

Generously season with salt and pepper, mixing it in to enhance the taste.

Transfer the guacamole onto a platter and mold it into a brain-like shape.

Drizzle a few drops of red food coloring over the molded guacamole, mimicking zombie veins.
