I like to cook with ESBIT because it is lightweight fuel.
** The more efficient the stove the less fuel you have to carry. That's a no-brainer.
> Caldera Cones appear to be the most efficient ESBIT stoves thus far for concentrating heat on the pot bottom as well as reducing heat loss from wind.
> Brian's Backpacking Blog shows how to make a better Gram Cracker fuel tablet holder that holds the liquid residue created when burning ESBIT tabs so it can all burn and extend burn time to about 15 minutes.
> Aluminum pots heat more evenly and rapidly than Ti pots and pots that are wider than they are tall are the most heat efficient.
With these efficiencies one gets the best out of ESBIT - faster boiling time/less heat loss, and longer burn times.
My personal ESBIT solo setup is CC Sidewinder Ti stove, 3 cup aluminum pot and homemade Brian Green design Gram Cracker tab holder.
I post all this boring info because, as my first posts on BPL years ago attest, I have been tinkering with ESBIT for years to get more efficiency. Now I have FINALLY reached "ESBIT Nirvana" - except for the gunk it leaves on pot bottoms, that is. :o)
P.S. Trail Designs includes both a Ti ground sheet (for burning wood) and a much smaller light aluminum sheet for under their Gram Cracker fuel tab holder. Now with the Brian Green improved Gram Cracker tab holder that saves the liquid residue I don't need the ground sheet but still carry the small aluminum sheet "just in case".
Stove Weight -> 1.5 oz. (includes Sidewnder stove,Tyvek stove storage sleeve, modded tab holder, aluminum base sheet)
3 Cup Aluminum Pot & Lid Weight -> 3.9 oz.
Stuff Sack, Plastic Bowl & Cup Weight -> 1.8 oz. (cut-down GLAD 'fridge bowl)
Total ESBIT Cookset Weight -> 7.2 oz.
For 5 to 8 day trips it saves me fuel and I carry less than I would with alcohol, alky stove and the Cone. I like to actually cook, as opposed to merely boiling water, hence the 3 cup pot.
