3 cups canned pureed tomatoes, San Marzano recommended
6 tbsp extra virgin olive oil
1 medium celery stalk, diced
1 medium onion, chopped
1 lb. tart green apples, like Granny Smith (3 medium apples)
1 lb spaghetti
3/4 cup fresh grated Parmesan cheese
salt to taste
Pour 4 tablespoons of the olive oil into a skillet on medium heat. Add the celery and onion to the pan. Cook until the onions begin to soften and caramelize, about 10 minutes.
Stir in the pureed tomatoes, season with a bit of salt. As the tomatoes begin to simmer, peel and core the apples, removing seeds. Shred the apples, using coarse holes of a shredder or grater.
When the tomatoes have cooked about 5 minutes, stir the apples into the sauce. Bring the skillet back to simmer, and cook the sauce uncovered for about 15 minutes, stirring a bit here and there, until it has begun to thicken and the apple shreds are cooked and tender.
As the tomato apple sauce cooks, bring a large pot of salted water to a rolling boil. Drop in the spaghetti, and cook it until al dente.
Strain the pasta when done to your liking and combine with the sauce. Toss the pasta with the sauce for a minute or two, until it is thoroughly coated and cooked just right. Turn off heat, sprinkle the grated cheese over the pasta and toss well. Serve the pasta immediately, passing extra cheese at the table. Enjoy with a glass of Italian red wine!
