How to Make Malt Sugar: A Comprehensive Guide

Malt sugar, or maltose, is a natural sweetener with a rich, honey-like flavor, widely used in Asian cuisine and baking. Making it at home is simple, requiring just two key ingredients: barley and rice. Here’s a step-by-step guide.

First, prepare the barley by rinsing it thoroughly and soaking it in water for 6–8 hours until it sprouts. Drain the water and spread the barley in a single layer on a tray. Cover it with a damp cloth and let it germinate in a dark, warm place for 3–5 days, until sprouts grow about 1–2 cm long.

Next, steam the germinated barley with glutinous rice (a 1:3 ratio works well) until fully cooked. Mash the mixture into a fine paste while still warm. Transfer the paste to a clean container, add a small amount of water, and mix well. Cover the container and let it ferment at 60–70°C (140–158°F) for 6–8 hours. During this time, enzymes will break down the starches into maltose.

Finally, strain the fermented liquid through a cheesecloth to remove solids. Simmer the liquid over low heat, stirring occasionally, until it thickens into a syrup. This concentrated syrup is your homemade malt sugar. Store it in a sealed jar in the refrigerator for up to a month.

From traditional Chinese tanghulu to modern desserts, malt sugar adds a unique sweetness. Experiment with different ratios or add flavors like ginger for a twist!
