Classic Burritos

I have been seeing double-wrapped burritos at a few places lately — one tortilla inside, one outside — and I cannot tell if it is a structural improvement or just a way to add bulk. My instinct says a properly sealed single wrap should be enough for most situations. When does double-wrapping actually make sense and when is it unnecessary?

My seal holds when I am holding it in my hands but as soon as I set it down on the skillet it starts to unroll. I have tried rolling it tighter but then I get blowouts at the ends. There seems to be a tension between rolling tight enough to hold and not so tight that it fails. Is there a technique for transferring the sealed burrito to the skillet without it unrolling?

Every burrito I make feels like a guessing game with ratios. Sometimes I end up with too much rice and the protein is lost. Sometimes the beans overwhelm everything else. I am looking for a baseline ratio to start from that I can then adjust by preference. Is there an agreed-upon starting point, or does it completely depend on the style you are going for?

I keep getting blowouts and I suspect I am overfilling but I do not have a good reference point. Most recipes just say things like 'a cup of beans and some rice' which is not useful for understanding the actual weight. Is there a generally accepted fill weight range for a standard 12-inch flour tortilla? And does the weight limit change with tortilla brand or thickness?

I have heard different things about this. Some people say cold filling causes the tortilla to crack or stiffen before you finish the fold. Others say it does not matter as long as the tortilla is warm. I have had mixed results and cannot tell if temperature is the actual variable or if I am just inconsistent in my technique. Does anyone have a clear position on this? Is there an optimal fill temperature and does it vary by filling type?

I have been putting things in more or less at random and it mostly works, but I keep seeing people talk about layering like it is a real thing. Is there an actual order, or is this one of those things people say because their grandmother did it?
