Simmer the Beans Until Tender
55 Mins
Gentle simmer, about 95°C (200°F)
Put the drained beans in a large pot with 1.5 litres of fresh cold water. Bring to a boil, skim off any foam, then lower the heat and simmer gently for about 55 minutes until the beans crush easily between your fingers. Scoop out 120 ml of the cooking liquid and set it aside, then drain the beans.
Keep the heat low and steady — a hard boil splits the beans and clouds the liquid.
Done when: Beans that squash easily with a spoon and no chalky centre.

Fry the Onion, Garlic & Cumin
5 Mins
Medium heat, about 175°C (350°F)
Heat the vegetable oil in a wide, heavy frying pan over medium heat. Add the diced onion and cook for 3 minutes until soft and translucent, then add the garlic and cumin and cook for 2 minutes more until fragrant.
Do not let the garlic brown — browned garlic turns bitter and will flavour the whole pot.
Done when: Soft onion, fragrant garlic, oil smelling warm and spiced.

Mash the Beans with Cooking Liquid
5 Mins
Medium heat, about 175°C (350°F)
Add the drained beans to the pan with half the reserved cooking liquid. Mash with a potato masher or the back of a wooden spoon, adding more liquid a splash at a time, until the beans are mostly smooth with a few whole beans left for texture.
Mash in the pan, not in a blender — a blender makes the beans gluey instead of creamy.
Done when: A thick, spreadable mash that still shows a few whole beans.

Fry the Mash Until Thick & Glossy
5 Mins
Medium heat, about 175°C (350°F)
Keep frying the mashed beans, stirring constantly, for about 5 minutes. The mash will thicken, darken slightly and pull away from the sides of the pan in a glossy mass. Season with the salt and taste — add a pinch more if the beans taste flat.
The beans thicken a lot as they cool, so stop frying while they are still a touch looser than you want.
Done when: A thick glossy mass that holds its shape on a spoon.

Rest, Garnish & Serve
2 Mins
Resting, about 60°C (140°F)
Take the pan off the heat and let the beans rest for 2 minutes. Spoon into a warm bowl, scatter with the chopped cilantro and crumbled cotija if using, and serve at once with warm tortillas.
If the beans stiffen while they wait, stir in a spoonful of hot water to loosen them again.
Done when: Creamy, hot beans that spread easily on a tortilla.
