Why we forecast sukuma wiki like a stock market

Sukuma wiki is the most reliable green in Nairobi, and still its price swings with rain. We talk to our five farms every week.

Their forecast, plus our trade orders, sets the menu a week ahead. When a crop is short, the recipe flexes to mchicha or spinach before the price reaches your invoice.

That is the Plan step of the Haraka System, and it is the reason a café can quote a price list and keep it.
