Add the staples, not everything
Do not inventory your kitchen. Add the things you cook with often and the things that go off: flour, rice, tinned tomatoes, the half bag of spinach. Fifteen entries is a useful pantry and takes about five minutes.
Quick and boring. Do it once while the kettle boils.
Point the camera at a barcode and the product comes back identified, which is faster than typing and less error-prone.
Roughly honest beats perfectly stale
Items carry status where it matters: running low, or expiring soon. That is the part with real value, because it is the thing you forget until you are standing in front of the fridge deciding whether the cream is still fine.
A pantry you update loosely once a week is far more useful than one you tracked precisely for nine days and then abandoned. Aim for roughly right.
Ask what you can cook right now
What Can I Make reads the pantry against your recipes and sorts them by how close you are. Recipes you can cook tonight come first, marked as having everything. Below them are the near misses, each showing how many things are missing.
The near misses are usually the interesting part, because one shop for two items often unlocks four recipes.
Send the missing items straight to the list
Pick a near miss and send what is missing to your shopping list. That is the loop closed: the pantry tells you what you are short of, the list gets it, and Shopping Mode takes it to the shop.
