How To Make Big Mac Sauce

Step 1: You will need

Hi, I'm Matt Kemp from the Underground Cookery School. I'm going to show you how to make a series of sauces. I hope you'll enjoy.

I'm going to show you how to make a perfect Big Mac sauce and, before I do that, let's have a look at the ingredients we are going to use. So, for a Big Mac sauce, we need fresh mayonnaise. This is very yellow because I've actually made it myself, it's just a combination of mustard, egg yolk and vegetable oil.

Heinz tomato ketchup, French's American mustard, 2 teaspoons of caster sugar, some diced onion and over here, I'm just going to do this, because it's a good way of showing you how to slice properly, if you just use your knife against your big finger. I have some finely diced dell, which is actually one of the key ingredients to this. First thing I'm going to do is take some mayonnaise, put that in the bowl and I'm going to add some ketchup.

I'm trying to use Heinz, actually. The traditional American mustard is French's, I'm trying to use that one. I've got few teaspoons of sugar, maybe just two.

Some onion, sort of diced up and a little bit of dell, and that goes. It's going to get a really good old mix-up. And I've got to tell you, definitely, that dell is what makes this sauce.

And what we're going to do now, I'm just gonna put that on this tray, just to give you an idea of consistency. There you have the perfect Big Mac sauce.
