Mine is almost the same as Swamp Yankees method:
- Cento San Marzano (Cento is real, don't pay extra for fakes).
- 1/4 cup of olive oil
- 1-2 teaspoons of red pepper flakes
- 1 tablespoon of dried oregano
I drain the tomatoes whole (give em a squeeze though to burst them) in a seize over the sink for a bit. Maybe 20 minutes. You really want the moisture low without losing tomato.
The into the food processor with everything else and pulse.
I've tried fresh oregano, honestly think the dried is better here.
