Set a wide, heavy pot over medium-high heat. Add the sliced sausage in a single layer and brown on both sides until the fat renders and the cut faces are deeply coloured. Remove the sausage and set aside, leaving the rendered fat in the pot. The cue: the sausage releases cleanly from the base and carries a dark, caramelised crust.

Reduce heat to medium. Add the onion and garlic to the pot and cook in the sausage fat until the onion is fully softened and translucent, without browning. The cue: the onion is limp, glossy, and carries the aroma of cooked alliums.

Add the crushed tomatoes and stir to combine. Cook for several minutes until the tomato has darkened slightly and the mixture has reduced and cohered. The cue: the raw tomato smell has cooked off and the colour has deepened to a brick red.

Return the browned sausage to the pot. Add the drained soaked kidney beans and pour in the water or stock. Bring to a boil, then reduce to a steady, low simmer. This is where the dish lives or dies: the pot must remain at a patient, unhurried simmer for two to four hours. The beans must soften to full creaminess and the sausage must surrender its smoky character entirely into the broth. A short simmer produces a thin broth and firm beans — a collection of ingredients in water, not a soup. The cue: the broth has turned a rich red-brown, carries visible body, and a spoon drawn through it leaves a momentary trace.

Add the diced potatoes and shredded cabbage. Continue to simmer until the potatoes are fully tender throughout and the cabbage has wilted into the broth. The cue: a knife tip meets no resistance at the centre of the largest potato piece.

6
If using elbow macaroni, add it now and simmer until cooked through and just tender. Season the soup with salt and black pepper. The cue: the macaroni is swollen, yielding to the bite without paste at the centre, and the broth is savoury and balanced on the tongue.

Ladle into deep bowls. Each bowl should show a rich red-brown broth with beans, potato, sausage rounds, and cabbage all visible at the surface. Serve immediately with thick slices of Portuguese sweet bread alongside for dipping. The cue: the broth surface carries a fine slick of rendered sausage fat and the aroma is smoky, tomatoey, and deeply savoury.
