I still use the stock Esbit stove with a couple of "ears" that go across the wide part to block wind. I only use one tab; if I see I need a bit more heat or longer burn, I drop a thin twig or few in through the small remaining crack between pot and ear. For the most part, though, an Esbit tab will just boil an MSR Ti Kettle 3/4 full of water, which is all I need for a freezer bag of Ramen and some tea.
