Select the substitute based on desired flavor, fermentation needs, and recipe type.
For liquid substitutes, measure equal amounts or adjust ratios as noted for Brown Rice Syrup or DIY Malt Syrup.
Thin honey or DIY malt syrup mixtures as needed and warm slightly if thick or crystallized.
Use the substitute in place of malt syrup directly in the recipe and adjust other liquids if the batter consistency changes.
Taste and check texture after baking or cooking to ensure desired malt flavor and browning effects.
