Portuguese Egg Tart Recipe Poster (Vintage) — AI Prompt

Generate a detailed vintage-style Portuguese egg tart recipe poster with hand-painted illustrations, elegant calligraphy, and step-by-step instructions — ideal for food blogs and kitchen decor. Use it as a Art Conceptuel starting point for GPT Image 2: keep the visual structure and style constraints intact, then swap in your own subject, brand, or scene.

This prompt is organized as structured JSON with fields such as type, subject, style, poster, header, layout, and color palette. Keeping that hierarchy helps the model separate the subject, layout, interface elements, and detail constraints.

Start with small changes to subject, scene, camera, and color, then generate a few variations to compare composition and detail without turning the page copy into keyword stuffing.
