Cheese Extract - How to Use it?

I've recently bought cheese extract (or essence - the seller didn't know the difference and the bottle says 'cheese flavour' and smells like a room full of cheddar).

I've never used it before but was sure there was something online for how to use it - but I can't find a thing. I just find recipes using cheese.

I imagine it's probably used to enhance the cheese flavour of dishes that can't afford to use much cheese but are their recipes that just use it as a flavour enhancer? My sister recently became dairy free (these diet fads are the bane of every family cook)and I thought it would be nice for her to have some flavours she likes.

Please help!

Best regards,

Amber
