A closer look at “Supermarket Miso Taste Test: Which Pastes Pass the Authentic Soup Test?”, exactly as the source publishes it. A recent taste test of supermarket miso pastes reveals a surprising inversion of the usual quality-price relationship, with some of the most expensive options being the least authentic. The test, guided by miso brewer Jono Hope of Scotland's Slow Sauce, used the traditional 'soup test'—mixing a teaspoon of paste with warm water—to evaluate flavor authenticity. Many premium-priced products were found to be synthetic imitations, cut with thickeners, colorants, acidulants, and preservatives, deviating from the traditional fermentation of soya beans, salt, and koji.
