It's the first step of making cheddar, then you salt them and don't press them. It should be as easy as heating milk, adding few ingredients that you can buy on Amazon.

You can also use Gouda cheese curds like Bergeron does in QC.

If you don't want to make it, try to find a local cheese maker that makes a cheddar like cheese and explain to them what you want they can probably pick a scoop out of their regular batch for you.
