What do you eat on the bike?

Digging this up again to save making a new thread. I'm training this year are I want to get on the track, before I used to do long rides but just for a bit of fun so to speak. I wasn't pushing myself so I found getting food right during a right easy enough, I've been spending loads of gels and bars which as a student I can't really keep doing. I'm thinking about making some home made flapjacks for some slow release energy but I also need something that is quick release on me too as I'm diabetic so when I hit a harder section of the ride my levels drop quickly. I have dextrose and glucotabs but they are crap on the bike unless I'm having a hypo and actually stop, on the bike you end up breathing in most of them as they powder up and leave you with an epic dry mouth. What do people use as an alternative to gels and cliff bars etc, I've heard Jelly babies are a good shout.

For a quick hit rather than slow release Kendle Mint Cake is really good. Basically sugar/glucose and mint flavoring. It dissolves easily in your mouth as you eat it so you don't get the powdery effect you get from the glucose or dextrose tablets.
