Preparing the Ingredients for Purple Black Bean Soup recipe

Soaking and Cooking Black Beans

If using dried black beans:

  1. Soak overnight in water to reduce cooking time and improve digestibility.
  2. Drain and rinse the beans thoroughly before cooking.
  3. Cook in a pressure cooker or pot with fresh water until tender.

If using canned black beans:

  • Simply rinse and drain to remove excess sodium.

Chopping Purple Vegetables

  • Slice the purple cabbage into thin shreds for even cooking.
  • Peel and dice the beetroot into small cubes for quicker softening.

Prepping Aromatics for the Base

  • Finely chop onion, garlic, and celery to create a flavorful base. These aromatics should be sautéed until fragrant and golden.

Making the Soup Base

Creating a Flavorful Onion and Garlic Base

  1. Heat olive oil in the soup pot.
  2. Sauté onions, garlic, and celery until golden and aromatic. This forms the flavor backbone of the soup.

Building Depth with Spices and Herbs

  • Add ground cumin, smoked paprika, and chili powder to the sautéed aromatics. Allow the spices to toast briefly, enhancing their flavors.

Adding Vegetables for Richness

  1. Add chopped beetroot and shredded cabbage to the pot.
  2. Stir well to coat the vegetables with the spices.
  3. Pour in vegetable stock and bring to a boil before reducing the heat to simmer.

Cooking Purple Black Bean Soup

Step-by-Step Cooking Process

  1. Prepare the Base: After sautéing the aromatics and toasting the spices (from Part 1), add the soaked and cooked black beans into the pot.
  2. Combine Ingredients: Add vegetable stock to the pot, ensuring the liquid covers all the ingredients. Stir to combine.
  3. Simmer the Soup: Bring the mixture to a boil, then reduce the heat to a simmer. Cover the pot partially to retain moisture while allowing steam to escape.
  4. Stir Occasionally: This prevents the beans from sticking to the bottom and ensures even cooking.
  5. Check for Doneness: Simmer for 25-30 minutes or until the vegetables and beans are tender.

Achieving the Perfect Consistency

Consistency is key for a satisfying soup. Here’s how to adjust:

  • For a thicker soup, allow it to simmer uncovered for the last 10 minutes to reduce excess liquid.
  • If the soup becomes too thick, add a splash of vegetable stock or water to reach your desired texture.

Adjusting Seasoning to Taste

  • Taste the soup and adjust with:
    • Salt for enhanced flavor.
    • A dash of lime juice for brightness.
    • A pinch of sugar to balance the acidity of the beetroot.

Blending for Texture

Choosing Between Chunky or Smooth Soup

  • Chunky: Leave the soup as-is for a rustic feel, showcasing the texture of black beans and vegetables.
  • Smooth: Blend the soup into a velvety purée for a more refined presentation.

How to Use an Immersion Blender

  1. Insert the immersion blender directly into the pot.
  2. Pulse until you achieve the desired consistency, blending a portion while leaving some chunks for texture.
  3. If using a standard blender, blend in batches and be cautious with hot liquids.

Tips for a Perfect Creamy Finish

  • For added creaminess, stir in a dollop of vegan sour cream or coconut cream after blending.
  • Garnish with a drizzle of olive oil for a glossy finish.

Toppings and Garnishes

Fresh Herbs: Cilantro, Parsley, or Chives

  • Sprinkle chopped fresh herbs on top of the soup for an aromatic and visually appealing garnish.

Crunchy Options: Tortilla Strips or Toasted Seeds

  • Add a handful of crispy tortilla strips, roasted pumpkin seeds, or sunflower seeds to provide a delightful crunch.

Adding Vegan Sour Cream or Yogurt

  • A swirl of vegan sour cream or unsweetened plant-based yogurt adds a tangy contrast to the soup’s earthy flavors.
