September is a perfect time to bring soup back into the kitchen. The beauty of a good soup is that you don’t necessarily need a recipe. Once you understand a few basic components, you can make countless variations using what you already have.
Start with an aromatic base. Onion is a classic beginning, often joined by celery and carrots. But you can change the flavor immediately by using garlic, leeks, shallots, peppers or ginger. Cook these ingredients in a little oil or butter before adding liquid to develop more flavor.
Choose your liquid. Chicken, beef or vegetable broth provides an easy foundation, while water can work when the other ingredients are particularly flavorful. Tomatoes, coconut milk or a little cream can transform the character of the soup even further.
Add something substantial. Potatoes, beans, lentils, rice, pasta or grains give soup body and make it more filling. Chicken, beef, sausage or other proteins can turn it into a complete meal.
Next come the vegetables and seasonings. This is where soup becomes especially flexible. Zucchini, corn and tomatoes can make use of lingering summer produce, while carrots, squash, potatoes and greens begin moving the pot toward fall. Herbs and spices can take the same basic ingredients in completely different directions.
Finally, pay attention to balance and finishing touches. Salt brings flavors forward, but a soup that tastes flat may actually need acidity rather than more salt. A squeeze of lemon, splash of vinegar or spoonful of tomatoes can brighten the entire pot. Fresh herbs, grated cheese or a drizzle of olive oil can be added just before serving.
Think of soup as a collection of building blocks: aromatics + liquid + substance + vegetables + seasoning + finishing touches. Change one or two pieces, and the same basic method can become an entirely different meal.
