Start by gathering all the ingredients mentioned above. It’s no fun looking for something in the middle of cooking. Set up your workspace so it’s organized. Clean and chop any items if necessary. This helps make the blending process smoother.

Using measuring spoons, scoop out the appropriate amounts of each ingredient. This is crucial for a consistent result. Too much vinegar, and your mayo might become overly tangy. Too little onion powder? You’ll miss that flavor. Precision matters here.

In a medium mixing bowl, combine the mayonnaise, white vinegar, lemon juice, and granulated sugar. Stir until it becomes a smooth mixture. Next, add the onion powder, ground mustard, and if you want it garlicky, the garlic powder. Give it another good stir to blend everything thoroughly.

Don’t be shy! Dip a spoon into your creation and take a taste. If it’s too tangy, add a pinch more sugar. Want it a bit thicker? Consider adding an extra spoonful of mayonnaise. This is your chance to perfect it to your liking!

Cover the bowl with plastic wrap or transfer the mayo to a jar with a lid. Let it chill in the fridge for at least 30 minutes. This allows the flavors to meld together beautifully. Trust me, the wait will be worth it!

Once chilled, spoon the onion mayo into a serving dish. Enjoy it on burgers, sandwiches, or as a dip for veggies. The options are endless!
