Which makes better sense for solo?

I've also gone back to just eating in my pot, precisely because of the mess involved in FBC. I still don't make anything that requires more than boiling water, though, and then I take the pot off the stove, add the food, and let it sit just like FBC. Afterwards, as long as you have a water source nearby you can clean the pot with untreated water, because you're just going to boil it next time anyway, which will kill any bugs from the untreated water.

This is one of the areas where I've "stepped back from the edge", so to speak. Like many, I went fanatical light at one point but have now decided where I'm willing to carry a little extra weight. Weight isn't really an issue on this subject, granted, but you get my point I hope.

I also moved back to using the pot for either cooking/eating or warm drinks, but not both, and I usually like to have provisions for both at breakfast and dinner.

I typically a double-walled or plastic mug for coffee and tea. The GSI infinity mug is a light (~3.5oz) and inexpensive choice. That way your drink stays warm while you are fiddling with food or something else. Boil water, transfer part to the mug, then finish cooking and eating from the pot. This also works great when cooking for 2. My son is less interested in hot drinks and just needs one mug or bowl for eating. I have an Evernew 1.3L that might be bigger than necessary, but doesn't weigh that much more than smaller pots. My son will carry another Infinity mug or a Snow Peak Ti bowl , and the bonus is the bowl makes a great baking pan inside the Evernew pot.

On a smaller scale, narrower pot/mugs are lighter and more packable. For years I used a Snow Peak mini-solo kit that has a ~10oz cup that nests outside the bottom of the ~24oz pot. I have a Toaks light 650 ordered from MassDrop due soon that will shave a few more grams. Narrow pot cozys are easy to make and light, but unnecessary if you are going to finish the cooking over your stove anyway. I haven't tried baking inside a narrow pot yet, but I have an aluminum fat daddios 3×3 pan ready for an upcoming trip. It nests inside the snow peak (and probably the Toaks), and doubles as a cup for hot liquids, albeit without a lid.

So many choices if you are willing to carry a couple more ounces. I probably said this before here, but I've tried the beer can pots and FBC, and there is a satisfaction in being extremely light. Others report no-cook trips – even lighter! I like to cook and I like the Ti options better now for durability and versatility – they can even be used on a fire if that's allowed where you camp.
