Great tip, thanks!

I can't speak to the one you replied to, but I adore this recipe - https://www.thespruceeats.com/taiwanese-beef-noodle-soup-4777014

For us it makes about 9-10 serves of broth and ~7-8 serves of meat, so we always have some in the freezer for an easy meal.

I've been using black beans in chilli oil as a sub for Mapo Tofu and a very similar Taiwanese Beef Noodle soup and they're god damn delicious!
