TogwaSweet fermented maize drink
In Tanzania's Dodoma, Singida and Iringa regions, togwa is drunk through the hot, dry months and carried to workers in the fields at midday. It starts as a thin porridge of maize or sorghum flour. Once it cools a little, a handful of kimea, sprouted and dried finger millet ground to a malt, is stirred in, and its enzymes turn the starch to sugar so the thick gruel thins almost before your eyes and tastes sweet. Left overnight, it sours lightly. Good togwa is sweet-sour, smooth and drinkable, like a thin, tangy grain milk. Any alcohol is only a trace, well under 1%, if drunk within a day or two. The common mistake is stirring the kimea into gruel that is still boiling, which kills the enzymes and leaves it stodgy; wait until it is hot but bearable to touch, about 60 °C. It is ready when it has thinned to a pourable drink, tastes pleasantly sour and smells clean and slightly yeasty. If you cannot buy kimea, soak finger millet for 12 hours, sprout it for 2 days, dry it in the sun or a cool oven and grind it. Chef's tip: stir in the malt in two goes, half while warm to sweeten and half when cool to start the souring.
