Who doesn't love a plate of nachos? Last night, after a Mother's Day BBQ with family early in the day, we were getting hungry. We had a lot of left over salsa and chips from the barbecue so I thought a plate of nachos sounded good. Of course I couldn't just plop all the stuff on some nachos and microwave it, I wanted to make a good nacho cheese sauce.
There is a specialty ingredient in this cheese sauce, sodium citrate that you can buy for like $6 on modernist pantry. Sodium citrate, or sour salt, is an emulsifying sodium salt that comes from citric acid. It has a sour taste and is usually used as a food additive for preserving or flavoring. All it does is help emulsify the cheese together. I also redid my salsa recipe a little bit, so check that out as well!
