  • I have some of those too. Problem is they’re nowhere near as efficient at cooling as ice cubes are and never cool my drink enough. It’s the melting (phase change) process that does the majority of the cooling with ice cubes, which you miss out on with these solid blocks.

    I forget the exact maths, but a quick googling reckons it takes something like 84kJ to change the temperature of 1kg of liquid water by 20K, but changing the temperature of the same amount of ice from 0K ice to 20K water takes nearly 420kJ, or roughly 5 times more energy, which is why they’re so much better at cooling drinks…



  • Coffee.

    I blame James Hoffman entirely.

    Within a year I went from:

    Drinking instant coffee at home, but really enjoying “proper coffee”

    To

    Buying a cafetiere (~£15) + preground coffee

    To

    Buying a Nespresso (~£60 on offer) + pods

    To

    Buying a budget espresso machine (~£120) + preground coffee

    To

    Wasting my money on a cheap manual coffee grinder (~£50) + beans

    To

    Immediately replacing it with an entry level Sage grinder (~£170)

    To

    Buying an entry Level “proper” espresso machine (~£700)

    It took me a good 2-3 weeks of practicing and dialling in before pulling a good shot of coffee that I’d actually want to drink, but by that point it was also about learning a new skill, learning how different aspects of the process affect the end result and learning how to make all sorts of different espresso-based drinks.

    My girlfriend thought I was nuts at first, but a year or so later even she agrees it was worth the investment. I still for the life of me can’t get the hang of latte art though.

    The problem is now though that I’m a waaaay more critical of coffee from coffee shops, because I spent a long time making bad coffee whilst learning!
