Smart Substitutes: Replacing {missing_ingredient} in This Recipe

You are halfway through and the one thing you need is not in the cupboard. Name the dish, the missing item and why you need a swap, and it ranks the three best substitutes by how well they cover the original's job, whether that is flavour, texture, binding or moisture. Each comes with the conversion ratio and any technique tweak.

I am making {dish_name} and I do not have {missing_ingredient}. The reason I need to substitute is {reason} (e.g. I ran out, dietary restriction, unavailable locally). Please suggest the three best substitutes ranked by how closely they replicate the original's role in the dish, whether that role is flavour, texture, binding, moisture, or something else. For each substitute, specify the conversion ratio, any technique adjustment needed (e.g. reduce heat, add earlier or later), and what trade-off I should expect in the final result. If no substitute is close enough to work well, tell me honestly and suggest how I might adapt the dish concept instead. I am cooking at {skill_level} level.
