How it’s done
One fixed day a week, one dish on the table is the child's responsibility: choosing it, helping buy it, preparing it, and — the non-negotiable part — serving it with pride.
Your role shrinks on purpose: at first you cook with their hands on top of yours; over the months you only supervise fire and knives; one day you discover you're just setting the table. The dish can be humble. Its status, not: it's thanked for and eaten as what it is, the contribution of a member of the household.
What it builds — the why
Autonomy with an edible, immediate result: planning, executing, serving. And something quieter: the experience of being needed in one's own family — which is different from being waited on by it.

What to watch for in your child
Does your daughter care more about the process (mixing, inventing) or the result (serving, getting the applause)? Give her version room. And resist the temptation to correct the dish in front of everyone: autonomy that's amended in public learns not to try.
