Does this duplicate content hurt me?
It might, and it might not. If you're a very new site with low authority, and the offending site is well established, there's a chance they'll outrank you. In this case, it's worth issuing a DMCA take-down notice.
If you're ranking above the site, then Google has properly identified your recipe as the original/official, and there's no need to worry. See: https://neilpatel.com/blog/myths-about-duplicate-content/
