A better measure as to whether the user found what they were looking for would be if Google checked if the user continues browsing through subsequent search results or not.
Google does check this. It’s called bounce rate and is just one piece of the SEO puzzle. Keeping users on your site longer before they “bounce” is another, so these sites are incentivized to keep you on the page for as long as possible because they know that it’s unlikely for a user to find the exact recipe they are looking for.
At this level of optimization even the 0.25s spent scrolling past a story is enough to make a difference... this is like "competitive swimmers shaving off their body hair" level SEO.
For me, at least, I typically don't follow the recipe. Very rarely am I looking for cooking instruction. I'm familiar enough with most typical cooking techniques that ingredient list and proportions, plus sometimes a quick glance at the steps, is all I need to get the job done. I'm usually modifying the ingredients on the fly as I cook the dish anyway.
When I am looking for cooking instruction, I find my existing library of trusted cookbooks to have a much better signal to noise ratio than Googled recipes sites on the web.
I wish there were some “intermediate” websites for cooking. There seems to be a missing middle, where I don’t know exactly to do, but know enough basics to only meed a little bit of direction.
Ie, not step by step, but more general. Let me improvise, but still guide me.
From an SEO perspective, yes.
Time spent on page will be less if the recipe is on the top.
