Justin, it's very nice of you that you want to encourage people to stick to core blocks, but this solution also lacks an essential feature for food bloggers: the Schema.org markup.

You've featured our Recipe Card Blocks plugin in the past, which does everything you have explained in this tutorial in seconds, and there is no need to copy/paste the block pattern for every new recipe. Also, I imagine it will be a little challenging to make changes to the design of all recipes at once.
