We had planned to cook our own one-pot dinners on this trip, at least some of the time. We were unable to do any cooking, however, and ended up carrying a cooking pot and our new so-called versatile stove 1500 km, without ever being able to find a gas cannister that would fit it.
After quite a bit of discussion and investigation before the trip, we left our liquid fuel (MSR Whisperlite Internationale) stove behind, having been told that running it on unleaded gas would ruin it, and we were unlikely to find white gas (Coleman Fuel) or kerosene. The stove we bought for the trip, an MSR Superfly, would fit “almost any canister” we were told by the lad at MEC. There would be no problems with different types of screw threads, he assured us. It attaches to the canister by gripping the rim. How clever! We were sold on the idea.
We couldn’t find any gas canisters with rims in Hungary, Croatia, or Serbia. They were all a rimless design. And we couldn’t find any gas canisters at all (other than 100kg propane tanks) in Romania.
If we travel in Eastern Europe again, we’ll take the MSR Whisperlite and find something combustible to feed it. We may shorten its life, but at least we’d have been able to cook a few meals.
