I assume two of you?

You did not say if you are locked into whatever you have used for a stove. Do you "cook" or just heat water? My point is that some stoves are great for boiling water (Jetboil or some of the pots with a heat exchanger), but if you are stirring a viscous liquid like a thick soup or stew, you need a different kind of stove that spreads the heat out more so the food does not burn onto that tiny little spot in the middle of the pot.

I do not recall what countries you are going to. It is my understanding that in France you may have difficulty in buying the threaded type butane canisters, but on this forum it was commented a few years ago that Decathlon stores sell the threaded canisters. Photo below, the canister on the left is not threaded, the canister on the right is threaded. If your stove is threaded, make sure you are careful when shopping in Europe.



Imi on this forum is more knowledgeable than I am for where to buy what kind of canisters in Europe.

Photo below is my solo cook kit from a bike tour six years ago.



In the photo above, starting at top left and going to the right, some aluminum foil, just in case it might come in handy. An older Primus stove that has a wide burner head, strainer for draining pasta (hot pad not shown, it is a folded bandana), measuring cut, small titanium mug that I also have used as a small pot for pasta sauce, green plastic bowl that nests in the pot, the plastic jar with a green lid is my instant coffee jar. Underneath the pasta strainer is a folding wind screen. To the right of that is a small fry pan that will nest inside the green bowl, that fry pan had a handled riveted to it which I removed, fry pan in a plastic bag to protect non-stick surface.

Starting at bottom left and going to the right, the white thing is a cheese slicer, the green thing is a spatula that I no longer use, there is a smaller white spatula to the right of that, a small vintage can opener, folding spoon and folding fork, knife with sheath, cork screw, pot gripper, wooden spoon, a coffee can lid which is my cutting board, a one person sized titanium pot, and my double wall coffee mug. The instant coffee jar fits perfectly in my coffee mug for packing.

I do not have a total weight on everything in that photo, but it has worked well for me. That said, I am starting to use stainless instead of the titanium for bike tours, I still use titanium for backpacking where I want the extra light weight. I think that this photo is from my last bike tour where I used the titanium pot instead of stainless. Stainless, it is easier to clean with a scrubby without damaging the surface of it, etc. And I do not worry about using a metal spoon in a stainless pot where I do not want to damage the surface of the titanium pot. Thus, the wood spoon for the titanium pot.

Soap and scrubby not shown. Fuel canisters were bought after I got off the plane, not shown. Food hanging rope and gear not shown.

I doubt that this would be any lighter than what you already use, I am providing this detail in case it lists things you did not think of. I carry a lot more on a bike tour than I do for a backpacking trip. When backpacking it is almost all dehydrated, no need for a fry pan.

If you are packing extraordinarily light and only using the stove to heat water, Gauvins on this forum had a long thread on a cook kit a year or two ago, he was very minimalist.
