Recently I've been making a spaghetti dish where wine is the protagonist. The cooking of the spaghetti is finished in a sauce (whose cooking already started, too) made with red wine, oil, garlic and chilli pepper, so that they absorb much of it. When they're done, I add black olives and soft-texture cheese with an intense taste, not salted and slightly bitter, and mix up. Finally, the whole thing goes in the plate where minced pistachio nuts are waiting.
I've come to the conclusion that I prefer a fortfied wine in here. Moreover, due to the pistachio nuts, I want a sweet aftertaste, but at the same time it should match the spicy flavour given by other ingredients. What are my European choices? I'd prefer cheap enough suggestions (maximum around 10 euros a bottle) but more complete overviews are welcome.
