Can I use it twice in the same post?

Sure! With WP Recipe Maker you add recipes as part of a regular post and you can add as many of them as you want: https://help.bootstrapped.ventures/article/67-creating-a-recipe

We are also compatible with WPML and Polylang if you’re looking for a multilingual site solution: https://help.bootstrapped.ventures/article/132-how-to-use-this-for-a-multilingual-blog

Thanks a lot for the speedy response! I’ll check that.
