Adding recipes manually and calories?

Unfortunately, you still need to check the auto-matched items carefully. It's always possible that the original web site is incorrect, but it's definitely true that the MFP auto-match will need tweaking at times.

Adjustments are possible in either web browser MFP or the phone/tablet app, but the specific mechanics differ. Not knowing which you use, I'll describe it in the web version, which I think is a little more inobvious in what to do. If you're using the app, and can't translate this to that environment, say so, and I'll take the time to do more screen grabs.

Here's the first few items from a random web recipe for lasagna. Obviously, the circled items matched are each wrong. (These are only a subset of examples of what can happen.)



In the next screen grab, I've already corrected the quantity on the first one, clicked "Edit Quantity" on the second but not changed it yet, and hovered my cursor to the right of the 3rd ingredient to show you the options that are hidden until you hover the cursor there. (The "Replace" link brings up a search box so you can find a better matching entry, or one with more correct calories/nutrients. I haven't show that here, but you can experiment.)



The phone/tablet app offers similar capabilities, but usually you're clicking on the item to change quantity or replace it via search, or deleting an item you don't like and adding others.

Once I vet the line items carefully in MFP, I figure I'm getting reasonable calorie/nutrient data. Generally, I have no idea how the recipe site derived their nutrition info, so I tend to trust it less than my carefully reviewed/edited MFP version. YMMV.

Best wishes!
