How to Make the Perfect Onion Cactus Blossom

Crafting this culinary showpiece can be broken down into a few main phases: preparing the onion, creating the batter, and frying it to a beautiful golden colour. We’ve laid out the steps clearly so you can follow along without any fuss.

Step 1: Preparing the Onion (The ‘Blossom’ Cut)

The signature ‘blossom’ shape is all down to how you slice it. This may seem daunting, but with a firm grip, it’s quite straightforward. The objective is to cut the onion into sections while leaving the root base connected, which holds all the ‘petals’ in place.

1. Peel the onion, being careful to leave the root end undisturbed. This is absolutely vital!
2. Trim about half an inch from the top (the non-root end) of the onion.
3. Set the onion on its cut, flat side on your chopping board.
4. With a large, sharp knife, make your initial cut downwards, starting roughly half an inch from the root and slicing all the way to the board. Be sure not to slice through the root.
5. Turn the onion 90 degrees and repeat the cut, forming four even quarters.
6. Continue to slice between your previous cuts until you have between 12 and 16 uniformly spaced sections, all joined at the base.
7. Gently flip the onion over and carefully pry the ‘petals’ apart with your fingertips. Work slowly to prevent them from snapping off.
8. For an even crispier finish, submerge the cut onion in a bowl of iced water for a minimum of 30 minutes. This encourages the petals to open further and firms up the onion. After soaking, drain it well and pat it completely dry with kitchen roll. A dry surface is key for the coating to adhere properly.

Step 2: Creating the Seasoned Coating and Wet Batter

The secret to our onion’s hallmark crispy texture lies in a two-stage coating method. We’ll prepare a seasoned flour blend and a liquid egg wash for dipping.

• For the dry mix: In a large bowl spacious enough to hold the onion, whisk together the plain flour, smoked paprika, garlic powder, cayenne pepper, salt, and black pepper. Ensure they are fully integrated.
• For the wet mix: In another, slightly smaller bowl, beat the eggs and milk together until you have a smooth mixture.

Step 3: The Double-Dredging Technique for Maximum Crunch

This is the crucial stage for that perfect crust. Dredging twice guarantees a substantial, tasty coating that will remain intact during frying.

1. Place your dry, prepared onion into the seasoned flour. Use your hands or a spoon to coat the onion all over, working the flour between each individual petal. Gently shake off any loose flour.
2. Now, immerse the flour-dusted onion into the egg and milk mixture. Once more, make certain the wet batter coats every nook and cranny. A ladle can be helpful for this. Lift the onion out and allow any excess to drip away.
3. Return the onion to the seasoned flour for its second, final coating. This is the most critical part. Be meticulous, pressing the flour blend firmly onto every surface, both inside and out. A generous coating equals a super crispy finish.
4. Once thoroughly coated, you can place the onion in the freezer for about 15-20 minutes. This step helps the coating to set firmly, ensuring it sticks better when fried.

Step 4: Frying to Golden Perfection

While deep-frying needs a bit of attention, it’s essential for getting that authentic, crisp finish. Maintaining the correct oil temperature is the key to success.

1. Pour the oil into a large, deep saucepan or a Dutch oven. You’ll need enough oil to submerge about half of the onion. Heat the oil over a medium-high flame until it registers 175°C (350°F). For best results, use a kitchen thermometer. If you’re looking for extra guidance on deep-frying, BBC Good Food has an excellent guide.
2. Using a large slotted spoon or a wire spider skimmer, gently lower the prepared onion into the hot oil with the cut side facing down.
3. Fry for 3-4 minutes on this first side until it achieves a lovely golden-brown hue. Then, with great care, turn the onion over and continue to fry for another 3-4 minutes until the remainder is a deep golden brown and the petals are perfectly crisp.
4. When it’s ready, carefully remove the onion from the oil, letting any surplus oil drain back into the pan. Transfer it to a wire rack positioned over a baking tray. Avoid placing it on kitchen roll, as this can cause the bottom to become soggy.

The Ultimate Creamy Chili Sauce Recipe

The onion might be the main attraction, but this blooming onion with dip truly shines with its partner. This sauce is incredibly simple to prepare and can be mixed together while the onion is chilling or frying.

1. In a small mixing bowl, add the mayonnaise, soured cream, sriracha, ketchup, Worcestershire sauce, horseradish, smoked paprika, and garlic powder.
2. Stir all the ingredients together until the sauce is smooth and uniformly blended.
3. For the most delicious results, cover the bowl and chill the sauce in the refrigerator for at least 30 minutes before you serve it. This gives the flavours a chance to meld and deepen.

How to Serve Your Onion Cactus Blossom

A big part of the appeal is in the presentation! To serve your magnificent creation, arrange it on a large plate or serving board. You can use a small knife or an apple corer to carefully remove the very centre of the onion, creating a space for a small dipping bowl of the creamy chili sauce. This not only looks authentic but also makes dipping easy for everyone.

This makes for an ideal starter to a meal that everyone will enjoy.

Instructions

1. Prepare the Onion: Peel a large sweet onion, leaving the root intact. Slice off the top. Cut downwards from near the root to create 12-16 wedges, keeping the base connected. Gently separate the ‘petals’ and soak in ice water for 30 minutes. Drain and pat completely dry.
