Recipe pages are often long. The good news: most of them hide a clean, structured copy of the recipe in the page's code, which apps can read.
Option 1: the "Jump to recipe" button
Many blogs have one at the top. It helps while reading, but doesn't save anything.
Option 2: print to PDF
Many sites have a print button with a cleaner layout. Save that to Files. It's tidy but hard to search or shop from.
Option 3: import into a recipe app
In Yumpair, copy the link and tap Paste a link, or tap Share → Yumpair in Safari. You get the title, photo, servings, time, ingredients and steps, ready to edit. From there you can send the ingredients to your shared grocery list.
