My son was rather shocked when he followed me making his favourite pasta sauce:

• 500g large onions peeled and cut in eights,
• 1kg carrots, peeled and cut into thumb-sized pieces,
• 1 large celery bulb, peeled and cut in rough cubes,
• a few spoons of salt to start the spicing process.

Fry in a large pot with a helping of olive oil. When veg starts to brown, add

• 1 tin (4.5kg) of chopped tomatoes,
• 1kg of leek, halved, cleaned, and cut in thumb-sized pieces,
• one bulb of garlic,
• 200g of Italian herb mix.

Let this simmer on low heat for 3-4 hours at least. Take the large blender and go through the pot. It does not have to be completely ground down, if small chunks still exist, it is fine.

Then take

• 3-4kg of minced beef,

And fry it in chunks of about 300g each in a pan while stirring into crumbs. For the first one or two pans use some oil. When browned, take a ladle of the sauce and add it to the pan. Stir until both parts are well integrated, then add them back into the pot - on one side, do not yet stir them under. For later pans, take off the fat that collects on the surface to oil the pan.

When all meat has been done like that, stir it under and let it simmer for another hour.
