One of McDonald's' biggest secrets may have just been leaked

When it comes to food, there are some mysteries that will forever remain unsolved.

KFC’s special blend of herbs and spices, for example, or what the meat is in that deliberately vague ‘meat and chips’ you got on your way home from the pub.

The same goes for McDonald’s’ Big Mac sauce… or at least it did.

A recipe has begun circulating on Pinterest, since shared by MailOnline, which purports to detail all 33 ingredients included in the sauce.

Yes, thirty-three. It’s both literally and figuratively a mouthful.

You might have a little trouble getting hold of all of these – or indeed using them for anything else once you’re done trying your hand at homemade Big Macs – but if you want to give it a go then look no further:

Soybean Oil, Pickle Relish (Diced Pickles, High Fructose Corn Syrup, Sugar, Vinegar, Corn Syrup, Salt, Calcium Chloride, Xanthan Gum, Potassium Sorbate (Preservative), Spice Extractives, Polysorbate 80), Distilled Vinegar, Water, Egg Yolks, High Fructose Corn Syrup, Onion Powder, Mustard Seed, Salt, Spices, Propylene Glycol Alginate, Sodium Benzoate (Preservative), Mustard Bran, Sugar, Garlic Powder, Vegetable Protein (Hydrolyzed Corn, Soy and Wheat), Caramel Color, Extractives of Paprika, Soy Lecithin, Turmeric (Color), Calcium Disodium EDTA (Protect Flavor).

Alternatively, according to Mom Deals, you can make your own version with just seven ingredients: mayonnaise, French dressing, sweet pickle relish, finely minced white onion, white vinegar, sugar and salt.

Or, y’know, you could probably just buy a Big Mac for less money than it’ll cost you to get all of that together. They’ll throw in the burgers as part of the deal, too, because that’s how Big Macs work.

But hey, whatever floats your boat.
