How does the shopping list work?

Open any recipe and tap Add to shopping list. You'll see a checklist of every ingredient — untick the ones you already have (or that you've marked as pantry staples) and hit Add. The list lives at /shopping in the top nav (or under *My Cookbooks*). Items are grouped by supermarket aisle — fresh produce, meat, dairy, baking, pantry — and any ingredient that appears in more than one recipe merges into a single row with a *from Recipe A + Recipe B* chip so you never buy twice.
