Walnut pesto is a sauce made by blending basil or parsley until it is smooth and creamy. Cheese can be added to the mixture, but it is not required. The walnuts are then added to the sauce, whether toasted or raw, whole or diced. Pesto is a classic Italian sauce that is frequently served over pasta, on toasted bread, or as a meat topping. Pesto comes in a variety of flavors, some of which vary by region, but the majority of them involve pulverizing leafy greens into a paste.
Pesto is mentioned for the first time in Genoa. Garlic, basil, pine nuts, olive oil, and grated cheese were the original ingredients. The basic recipe has remained largely unchanged, but new ingredients have emerged that have expanded the pesto’s flavors and applications. Walnuts have long been a part of Italian cuisine, so it’s no surprise that they’ve made their way into this classic dish.
Cooking with walnuts isn’t difficult, but it does necessitate the acquisition of a good-quality ingredient. Walnuts, like most nuts, contain oils, which means they can easily go rancid if left on a shelf for too long. If they are not going to be used within a few weeks, they should be stored in the refrigerator or freezer.
It’s a matter of personal preference how the walnuts are used in the dish. To develop their flavor, they are sometimes roasted in an oven or browned in a pan. They can also be used to add texture to the walnut pesto, either raw or diced.
Pesto can be made with basil or other greens, such as spinach, as is traditional. Popular choices include parsley and arugula, or any combination of the two. Onions and garlic, for example, can be added to taste. The ingredients were mashed into a paste with a mortar and pestle in the earliest pesto recipes. As a result, the word “pesto” literally means “paste,” despite the fact that food processors have made mixing the ingredients much easier.
The nutritional value of the combination of ingredients is high. Vitamins A and K, as well as calcium and potassium, are all found in basil. Omega-3 fatty acids are also present. Thiamin, folates, and vitamin B6 are all found in walnuts. Walnuts also contain a significant amount of protein.
Walnut pesto is usually made at room temperature and only heated up when served over hot pasta. Cooking is required in some recipes, such as when it is used as a coating for pork or other meats. When making walnut pesto, it’s critical to keep the walnuts from burning and the pesto from breaking as it heats.
