What a good idea hummus would be on a ride! We make it at home all the time in the summer but I never thought about a "to go" cup of it. I personally wouldn't worry at all about spoilage - after all, I would think plenty of people in it's land of origin don't have refrigeration and it's plenty hot there! It's just garbanzos, tahini (ground sesame seeds), garlic, lemon juice and olive oil. No eggs or anything. But I understand the concerns about being careful!
