This is the type of caffeinated recipe that I can't eat much of (since I am caffeine-free!), so I made it while my special gentleman was in town last week. The recipe was incredibly simple. Instant espresso powder, cornstarch, sugar, and salt were mixed with hot milk. This mixture was then chilled in the refrigerator and then frozen in the ice cream maker. The flavor of the resulting gelato was excellent, but the texture could have been better. Often homemade ice cream is made with either whole eggs or egg yolks. The eggs give the frozen dessert a creamy, custardy texture. In cases like this, where the recipe is made without eggs, it is more prone to freezing with some small ice crystals in it. So instead of the rich, creamy texture one might hope for, this recipe was a little bit icy. That said, the flavor was fantastic. The gelato had a great coffee flavor, and just the right touch of sweetness to balance it without it being overpoweringly sweet. Although it is possible to make a better coffee-flavored ice cream than this one, this is still a great simple recipe, which produces a tasty frozen treat.
The recipe in The Book is very similar to this one.
It never ceases to amaze me how fast technology changes. I took calculus about 10 years ago now, and I remember being assigned problems from the textbook. I wrote solutions on notebook paper, submitted them to my teacher, and they were graded by hand and returned to me. Times have changed. My business calculus students do online homework. I choose problems from a bank of problems, and each student gets slightly different questions (to prevent copying). The students can attempt to answer the questions as many times as they want, and each time they submit an answer they are told if it is correct or incorrect. If it's incorrect they can try again. As long as they submit the right answer before the deadline, they get full credit. This type of homework system was totally new to me when I started teaching at Indiana University last year.
This semester I have one student who brings his laptop to class every time and does his Webwork during lecture. It doesn't bother me -- he's a good student and if he wants to get his homework done during class that's ok with me. Sometimes he asks Webwork problem-inspired questions during lecture to confirm that he is working on his homework and not just writing emails. After class a few weeks ago I had a student come up to me and say, "I have a question about my Webwork, will you look at it?" He was clearly not carrying a laptop, so I said, "Do you have it printed out?" He looked at me like I was from the stone ages and responded, "I have it on my phone." Indeed, he was holding an iPhone, with his Webwork assignment on it. It was very convenient (aside from the fact that the screen was so small it was hard to see the whole problem at once!). I helped him with his problem in a few minutes after class and he went on his way.
It's crazy though, right? So much can change in such a small amount of time. I wouldn't have believed, a decade ago, that calculus homework would be done through a system online and someone would be carrying a tiny phone in their pocket that could access it. Craziness!
