For me, the amount of effort has everything to do with the amount and type of fuel I need. If I eat a decent meal a couple hours ahead of time I only need a PB&J to go all day on most rides. If I am climbing a lot or pushing my pace, I need to add jell or something every hour or so keep going. There are a lot of hills around here and few chances to buy food at convenient times. I carry more than I need always.
I am going to try that potato recipe. It's easier to remember to eat things that taste good.
