For a few weeks, my local McDonalds was selling a burger called the "1955 Burger", which had a really delicious sauce with lots of other things mixed in. I tried buying various BBQ sauces in the stores, but none had a similar taste.
What kind of BBQ sauce can I buy that will be close to what McDonalds uses? What other ingredients did McDonalds mix into the BBQ sauce?
Doing some research, I've found that some time ago, German McDonald's partnered with Develey to release bottles of the 1955 sauce. After putting it through Google Translate, the ingredients list reads:
Water, rapeseed oil, tomato paste, glucose-fructose syrup, sugar, sour cream, spirit vinegar, egg yolk, salt, modified corn starch, spices, caramel sugar syrup, natural flavouring, yeast extract, thickener (E415), smoke flavouring (source)
This pretty closely matches the descriptions of it here as a tomato-based smoky barbecue sauce, and is probably a good starting point for experimenting yourself (as I've never had the sauce before).
