Brian here is the recipe I use. I developed it myself and it turned out so good I had no need to change anything. My wife finds it a bit too much for the amount of capers but I'm fine with it. Amazingly all those strong flavours blend together quite well without being overpowering. You need some capers for sure, but you could always cut back on it. I use half a jar. Fresh parm is a must, it makes a big difference. I tbsp of pepper flakes has a nice tingle, two is fairly hot but still ok for me. Manitoubass2 tried it and thought it was great.
Puttanesca.
1/3 cup evoo
4 cloves garlic coarsely chopped (1 small bulb in my case)
1-2 tbsp red pepper flakes
I can (50g) anchovie fillets, rinsed and finely chopped
3 tbs capers, rinsed
25 pitted kalamata olives, rinsed, medium chopped.
1 540ml can diced tomatoes
1 540 ml can crushed tomatoes
4 green onions, medium chop (or onion of choice)
2 more cloves of garlic, squashed and finely chopped. (just because I wanted to add some real fresh garlic flavor at the end)
3 Tbs basil flakes
Chopped mushrooms and red/green pepper (optional)
Fresh grated Parm for the plate
Fry anchovies, garlic and pepper flakes in oil until garlic is golden (medium heat)
Add tomatoes, olives and capers and heat to light simmer. Whisk to incorporate oil.
After 5-10 min add onions, basil, extra garlic and optional ingredients if using.
Simmer 5 -10 minutes more and serve with desired pasta and choice of meat if using. (shrimp, fish ,sausages, chicken etc)
Cheers
