Follow-up: What's great about d'amatriciana: You don't have to worry about the amounts of ANYTHING. I use two-3 cans of Muir Glen organic diced. But any old canned tomatoes will do, just not the kind with other adds.
What I love: you almost always have most of this stuff in the house. It actually works for guests, too. People think it tastes special -- because most italiano food has beef/oregano in it. The bacon/onion/basil combo, with the peppper, takes it away from the usual Carmines Siciliana taste. This is a Romana first course pasta, but here, a great, cheese-ladden main dish!
The ratios are so not important. It can be chunky with more tomatoes, and less juice, or "runny" with lots of juice. Still tastes great. Honest. Use as much bacon as you want, and double the onions, reduce the garlic if you prefer. I've done it with more onion, no garlic, and it's just as good. You can't go wrong. And you can make it, like two hours earlier, or a day before, and just heat it up and dump it on the pasta. When made a day before, it's damned good. The whole combo blends even better.
Somebody here -- Ifitfloat, mynameinlights -- make it and tell me how it goes. Add bread and salad, and you'll love it. I swear by little in life, but this dish is a pleaser.
