Step‑by‑Step Instructions for Blooming Onion Sauce
Step 1: Combine the Base Ingredients
In a small mixing bowl, add ½ cup of mayonnaise, 2 tablespoons of ketchup, and 1 tablespoon of prepared horseradish sauce. Using a whisk or a spatula, gently mix these ingredients together until the mixture becomes smooth and creamy, resembling a soft pink sauce. This will be the delicious base of your Blooming Onion Sauce.
Step 2: Add Flavorful Seasonings
Next, incorporate the seasonings by adding ½ teaspoon of granulated garlic, ½ teaspoon of smoked paprika, ¼ teaspoon of ground cumin, and ¼ teaspoon of dried oregano to the bowl. Then sprinkle in ½ teaspoon of kosher salt and 1 teaspoon of black pepper. Mix well until all the ingredients are thoroughly combined, and the sauce takes on a rich orange hue.
Step 3: Chill for Flavor Development
Cover the bowl with plastic wrap or a lid to prevent any contamination and place it in the refrigerator. Allow the Blooming Onion Sauce to chill for at least 30 minutes. This resting period is essential as it allows the flavors to meld together, enhancing the overall taste and ensuring that each dip bursts with flavor.
