Smooth Beef Ragu

• 1 lb (450g) ground chuck, 80/20
• 1 medium yellow onion (~200g), grated on the large holes of a box grater
• 1 medium carrot (~80g), grated on the large holes of a box grater
• 1 celery stalk (~50g), minced as fine as you can or blitzed to a paste
• 3 garlic cloves, grated or minced fine
• 2 tbsp (32g) tomato paste
• 1 cup (240ml) whole milk
• 700g passata (strained tomato puree), or a 28oz can of crushed tomatoes blitzed smooth
• 1 tbsp olive oil
• 2 bay leaves
• 1 parmesan rind (optional)
• 1 tsp red wine vinegar (optional, to finish)
• Kosher salt and black pepper
• Rigatoni or shells, to serve (~100g dry per person)

Method

1. 1
   Grate the aromatics

   Grate the onion and carrot on the large holes of a box grater straight into a bowl. Mince or blitz the celery as fine as you can get it - celery is stringy and will not dissolve like the other two, so this is the one that needs real attention. Grate the garlic separately; it goes in later.

2. 2
   Sweat the base

   Olive oil in a heavy pot over medium-low. Add the grated onion, carrot, and celery with a pinch of salt. Cook 12-15 minutes, stirring now and then, until it has slumped, gone glossy, and stopped smelling raw. Do not brown it - you are driving off water and concentrating sugar, not searing. Add the garlic for the last minute.

3. 3
   Brown the beef

   Raise heat to medium-high. Add the chuck and break it up hard with a wooden spoon or potato masher as it cooks - the finer you break it now, the smoother the finished sauce. Cook until no pink remains and some of it has caught color, 8-10 minutes. Do not drain the fat; it is the sauce's body.

4. 4
   Brown the tomato paste

   Push the meat aside, drop the tomato paste into the bare pot, and let it cook 2-3 minutes until it darkens to brick red and starts sticking. This is where the depth comes from - it is doing the job wine would otherwise do. Stir it through the meat.

5. 5
   The milk step

   Pour in the milk. Simmer, stirring occasionally, until it has almost entirely cooked away and the meat looks coated rather than wet, 15-20 minutes. It will look curdled and wrong partway through - that is correct, keep going. This tenderizes the grind and rounds out the acid to come.

6. 6
   Add tomato and simmer

   Add the passata, the bay leaves, and the parmesan rind if using. Season with salt and pepper. Bring to a bare simmer - the occasional lazy bloop, not a boil - and hold it there uncovered for 60-90 minutes, stirring every 15 or so. It is done when the fat has separated out and pools orange at the edges, and the sauce mounds on a spoon instead of running off it.

7. 7
   Finish

   Fish out the bay leaves and rind. Taste. If it reads flat or too sweet, the vinegar goes in now, off the heat, a teaspoon at a time. Salt to taste.

8. 8
   Serve with the pasta

   Cook the rigatoni one minute short of the box time. Reserve a cup of the pasta water. Drain, then add the pasta to the sauce (not sauce to pasta) with a splash of the water, and toss hard over medium heat for a minute until the sauce clings and the water has emulsified the fat into it. This last minute is what makes it cling instead of slide.
