About this recipe Italian Sweet and Sour Peppers
This recipe is adapted from Gennaro Contaldo’s Passione.
Genaro’s recipe only used two peppers but if you are going to make something like this which improves on the second and third day, it makes sense to have a larger quantity. Really this is a guide more than a recipe. Add as much or as little of each ingredient but it must be sweet and it must be sour so don’t skimp on the sugar and vinegar.
Another tip is to take care with the cooking. Don’t saute over a very high heat, otherwise the peppers will burn. Similarly, too low of a heat or placing the lid on the pan, will cause the peppers to sweat, become mushy and the skins start to peel off.
Which vinegar is best for this recipe?
Reading through Gennaro’s book, he talks of his childhood growing up in a small village on the Amalfi coast. His love or “passione” of food is so evident as he explains about the ingredients. When it come to vinegar he says he likes to make his own red wine vinegar by putting some dry pasta into leftover red wine. Left for 20 days apparently it will to turn into vinegar.
Growing up, my father always made his own red wine vinegar. He loved pottering around in the cantina where he kept the vinegar. Our cantina was not the Italian underground wine cellar but an Australian windowless room off the garage that was used for storage of wine, homemade passata and of course, dad’s many bottles of vinegar in production. I loved that vinegar and have never been able to reproduce it maybe I’ll try Gennaro’s method.
Good quality red wine vinegar. even if it’s not homemade, is the best vinegar to use in this recipe.
How to eat these Sweet and Sour Peppers.
I love these sweet and sour peppers warm or cool. Take the dish out of the fridge a little bit before you want to eat to get the chill off the peppers. These make a great side dish to grilled, barbequed or roast meats like my butterflied roast chicken. As well, a bowl of these peppers with bread makes a perfect antipasto. Why not include a bowl of marinated eggplant to complete your antipasto?
Which coloured peppers are the best to use?
Here in Australia we are in the middle of summer and peppers (or capsicums) are almost at the end of their prime. Use the red ones or mix it up with the different colours but make these Italian Sweet and Sour Peppers soon before the season ends.
Baci,

I tweaked it a little. Used green pimento stuffed olives. Didn’t use any vinegar. Added breast chicken with a light seasoning pan fried & sliced just before completely cooked to peppers when cooked. Served with brown rice & quinoa.
Fantastic flavours. Really yum.
Next time I’d add less oo
Kathy, I like your tweaks! This is delicious with chicken!
I made is with peppers I roasted on my gas flame and rubbed the skins off of. It is totally delicious.
I’m sure it would have been amazing! I love roasted peppers!
Hello Marcellina,
How long does this keep in the refrigerator? And if it does, would one just take out to return to room temp before serving?
Hi Michelle, this would keep easily 4 or 5 days maybe longer. It can be eaten directly from the refrigerator (which is nice in summer) or return it to room temp or heat it before serving. Thanks for stopping by xx
I agree with you about making more than a single batch as I’m sure it quickly disappears.
Yes, Karen, I always like to make large batches of this type of dish!
ciao Marcellina, sono Stefano from Italianhomecooking (I have replied to yr comment about the torta di zucca/apologies for the replaying so late: generally I am on top of the messages…)
… anyway.. lovely, delicious recipe. I make the same basically, but i peel the pepper first (something I learn many many yrs ago from Marcella Hazan)… I love the agrodolce because it gets better as it sits: ideal dish to make in bulk/it is very versatile… on bread, with eggs, pasta, rice, panini ecc…
Gennaro is very good indeed: about 20 yrs ago I worked in the shop-deli where he used to bake and to be able to sample his focaccia and pizzette every day was a real treat.
on vinegar: very misunderstood ingredient: good vinegar can make a huge difference. it is very difficult here in London to get good vinegar (aceto di Barolo, for instance: wonderful), the best is generally sherry vinegar. However I learnt a trick from Richard Olney to transform bog standard vinegar in something super: u boil down a couple of lt of supermarket vinegar to its half volume, then u simmer it with … the world: shallots, garlic, sage, rosemary, basil, pepper, thyme ecc… then u filter the lot: it makes the most excellent vinegar (also: have u ever tried raspberyy vinegar: it is very good and it can be made also out of season using frozen berries/it lends a beautiful fruity note.. I sometimes use it also on vanilla ice cream!)
ciao
