Let’s Make it together
Get ready to roll up your sleeves and transform that humble onion into a culinary masterpiece!
Prep Your Onion: Start by carefully peeling off the outer skin of your onion. Cut off the top but leave the root intact—it helps hold those lovely petals together while frying.
Slice It Up: Place your onion cut-side down on a cutting board. With sharp knife skills (or an intense determination), slice downward about 1/4 inch apart without cutting all the way through. You want these petals to separate beautifully.
Dunk Time: In one bowl, whisk together buttermilk with some spices for extra flavor. In another bowl, mix flour, cornmeal, and remaining spices until well combined.
Coat That Beauty: Dip your sliced onion into the buttermilk mixture first, ensuring it’s fully submerged. Then gently coat it with your flour mixture—make sure each petal is covered!
Fry Away: Heat oil in a deep pot until it reaches 375°F (190°C). Carefully lower in the coated onion and fry for about 3-5 minutes until it’s golden brown and crispy.
Sauce It Up! While your blooming onion cools slightly (if you can resist), whip up your dipping sauce by combining ketchup, horseradish sauce, and lemon juice in a small bowl until smooth.
Enjoy every crispy petal dipped in that tangy sauce—it’s beyond delicious!
With this blooming onion recipe under your belt, you’ll not only impress everyone around you but also create unforgettable memories over shared laughs and crunchy bites. Whether you’re hosting friends or just treating yourself on a cozy night in, this recipe is bound to become a favorite!
