Can you buy big tasty sauce?

It doesn’t look like you can buy big tasty sauce online. There are many outlets selling burger sauce but this is more similar to the sauce found on big macs rather than the one found on big tasty’s.

What is the difference between the Big Mac and big tasty sauces?

The main difference between the two sauces is that the tasty sauce has a much smokier finish. This is achieved with the use of liquid smoke. However, if you cannot find liquid smoke you can substitute it for smoked paprika and achieve a similar finish.

Where can I buy Liquid Smoke?

Liquid smoke can be bought online and comes in a number of different varieties. The one we used in our recipe above was the Colgin Liquid Smoke Natural Hickory. We found this variety complemented the other ingredients and really made this sauce shine.
