4 cups homemade chicken broth

rendered chicken fat or other fat

2 onions, diced

3-4 cloves garlic, sliced

salt and pepper

1 cup pureed tomato, or to taste

red wine vinegar

Melt the fat (I scraped the fat off the chicken broth) and add the onions. Fry the onions and garlic until tender. Add the tomato and cook for a couple minutes. Add the chicken broth, bring to a simmer, and simmer for 10 minutes. Puree with a stick blender. Season to taste with salt, pepper, and red wine vinegar. Eat.
