I love Black Beans, they're my favorite and i'm very happy to hear there are some fans out there too like myself
This particular recipe was taken from my mom, she likes the taste of onion, but she hates to see it or acually bite it in the food, lol.
So for her it was much better to just give the onion flavor for both the oil for the beans and the water for the rice instead.
It's a different and more subtle taste. But always delicious!
Hope you enjoy making it just like me, i eat it at least once a week
