Sharon, I am at 86-87 kg, and I am not really watching my weight, except out of interest. So, I don't care if having a treat once or twice a week, means I weigh a little more, although honestly, it's not working out that way for me. It's good advice in general, but, I've never had a target weight.
I have a Sunbeam ice cream machine, the recipe was cream, milk, egg yolks, cocoa and dextrose. The ice cream was churned in the machine, I'm not sure how it would go without the machine.
