Yes, you can substitute matcha for green tea in recipes, but adjustments are necessary due to their different forms and intensities. Because matcha is a concentrated powder and green tea is a liquid infusion, direct substitution requires careful consideration.
General substitution guidelines:
Keep in mind that matcha will produce a more vibrant green color and bolder flavor in your recipes. It works exceptionally well in lattes, smoothies, ice cream, and baked goods. When substituting in savory dishes, use culinary grade matcha rather than expensive ceremonial grade.
