This recipe is so easy and delicious, I don't know why the canned version exists. Homemade refried beans transforms any meal from good to great... trust me.
In a medium stock pot over medium-high heat, melt the butter and lard.
½ cup Lard or bacon grease, 2 tbsp Unsalted Butter
Drain beans.* Add the beans to the melted lard.
2 cans 15 oz Black Beans, drained
Allow everything to come to a gentle boil and warm throughout.
After about 5 minutes, use a potato masher and start to mash beans (right in the pot over heat). Once they're partially mashed, let them simmer a bit longer. Adjust the heat AND stir so they don't burn.
Mash the beans again (and again) until they are a smooth texture. Taste them and add an appropriate amount of salt.
Salt
Serve them warm with tacos, bean dip, fajitas, etc. Will keep in the fridge up to one week.
Notes
*If you're using soaked beans, rinse them. It's not necessary if you're using canned.
