@Makiwa, I will be happy to explain any terms in your American cookbook that are unclear. I have a recipe for brownies from scratch made with melted chocolate chips that I've given out so often on MN that I created a British version of it. I'm happy to share it with you too if you like baking and chocolate. 
I am also surprised that your DC knew about half and half. That lovely coffee additive is unfamiliar to most people on MN. I may have to make a fresh cup of coffee now that I'm thinking about it.
I'm working from home today due to the ice storm that's due shortly.
I received a late Christmas present last night. DH had ordered me an Amazon Echo Show, the one with the built-in screen, but it was back-ordered and just arrived last night. I've had great fun setting it up. There are some brilliant weather skills (apps) for it, which appeal to the amateur meteorologist in me. I'm trying to find a way to get my weather station data to show up on it, but no luck so far.
