Hey, @hannahkay I'm a big fan of sweet potatoes :)

Maybe you found the bad quality sweet potatoes when the taste is bitter. I often get bad sweet potatoes too :) It tasted bitter from being hit by pests. Avoid buying sweet potatoes that have bigger black spots

A nice recipe that I never try because I rarely get chickpeas stocks. In here so expensive too. Roasted sweet potatoes are my fav too.
