well, if they read braille, they're unlikely to follow a video recipe...
A good idea if they cook though sure.

Is your friend literate in Braille? If not, an eBook might be better (assuming it’s compatible with screen readers). Or finding him a few cooking shows on YT or via podcasts that are specifically for blind people.

Make sure your friend reads Braille first. Not all blind or low vision people do. It might be a great idea if they’re a Braille reader. Otherwise an ebook or large print cookbook is probably a better idea.

Or a curated list of video tutorials that you know work and make something delicious, and the cook says what they’re doing instead of text on screen (as your friend may not be able to see it). There are definitely some good ones, but also some that are crap, or even dangerous, if we’re talking about YouTube tutorials.

Are you aware how huge braille volumes are? Who uses physical braille anymore? Give them an ebook if they’d like they can then hook on a braille display and use it that would be my best advice eText is much easier to handle. And besides braille books can be huge even a smallish cookbook can be a few volumes.

I for sure think it's a good idea. One year for Christmas my mom gave each of us three kids a binder full of family recipes (plus mine digitally available) I then became much more interested in cooking and know 15 or so different meals.

Find out whether they like to use braille first. A lot of low vision and blind people prefer e-books and videos these days

Are braille cookbooks glossy like text cookbooks? In case of spillage or wet hands.

I use a tablet for recipes and it's awesome. And also less expensive.
