Yes, rotis can be partially cooked and stored for later use. Cook them until they are slightly firm but not browned, then cool and refrigerate.
Partially cooking rotis involves cooking them on a hot tawa (griddle) until they are just firm enough to hold their shape but not fully browned or puffed up. This usually takes about 30-45 seconds per side. Once they are partially cooked, allow them to cool completely to prevent condensation. Stack the cooled rotis with parchment paper or a clean cloth between each one to prevent them from sticking together. Store them in an airtight container or a zip-top bag in the refrigerator for up to 24 hours. When you're ready to eat them, simply reheat them on a hot tawa, flipping occasionally, until they puff up and are lightly browned. You can also apply a little ghee or butter while reheating for added flavor and softness. This method is convenient for meal prepping or when you want to save time during busy weeknights.
When reheating, lightly sprinkle the roti with water before placing it on the hot tawa. This helps to create steam, making the roti softer and more pliable, preventing it from becoming dry or brittle.
