1. Bring a large pot of salted water to a boil and cook the spaghetti until al dente, according to package instructions. Reserve 1/4 cup of the pasta water, then drain and set aside.
2. In a large skillet, heat the olive oil over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant.
3. Add the fresh cranberries to the skillet and cook until they start to soften and burst, about 4-5 minutes. Stir occasionally.
4. Reduce the heat to low and add the cooked spaghetti to the skillet, tossing gently to combine with the cranberries and garlic.
5. Stir in the ricotta cheese, reserved pasta water, and half of the Parmesan cheese until the pasta is well coated and creamy.
6. Season with salt and pepper to taste. Sprinkle with chopped basil and the remaining Parmesan cheese before serving.

Cooking is an art of improvisation. Feel free to adjust the seasoning or add a splash of lemon juice for an extra zing, just like my abuela would do using her instincts.
