Here's a video giving a detailed and official way to make a Big Mac burger at home. It's part of a new McDonald's ad campaign in Canada that basically says "Hey, look at us, we're not evil".
Anywho, since they posted the video but somehow forgot to post a list of ingredients I'm going to try my best to write them down.
Big Mac Sauce:
- Sweet pickle relish
- Classic yellow mustard
- White wine vinegar
- Garlic powder
- Onion powder
- Paprika powder
Just a regular large bun cut into three pieces and toasted on the stove
I guess you'll have to try different mixes of the quantities yourself. I'd say he's using about 4 deciliter of mayo, 1.5 deciliter of sweet pickle relish, 0.5 deciliter mustard, a teaspoon of white vinegar and like a couple of grams of each spice. But my guess is as good as yours.
Anywho, I wish you luck if you're going to try it. I'm thinking of trying it right now.
Edit: I found that 2.5 dl mayo, 0.5 dl of pickle relish and about 0.2 dl of mustard worked really, really, well. took a tablespoon of the spices and vinegar each.
