The ideal rice flour to water/coconut milk ratio for soft, layered Puttu is approximately 2:1 (2 parts rice flour to 1 part water or coconut milk). This ensures the Puttu is moist and holds its shape without being too sticky.
Achieving the perfect Puttu texture hinges on the correct rice flour to liquid ratio. Here's a breakdown:
Rice Flour Preparation: Use good quality, finely ground rice flour. Some prefer roasted rice flour for a slightly nutty flavor and improved texture. If using store-bought flour, consider lightly roasting it in a dry pan over low heat for a few minutes until it's fragrant. This helps remove excess moisture and prevents the Puttu from becoming gummy.
Liquid Choice: You can use either water or coconut milk. Coconut milk adds richness and flavor, resulting in a softer Puttu. Water provides a more neutral taste, allowing the rice flour's flavor to shine through.
The Ratio: Start with a 2:1 ratio of rice flour to liquid. For example, if you're using 2 cups of rice flour, begin with 1 cup of water or coconut milk.
Mixing: Gradually add the liquid to the rice flour, mixing with your fingertips. The goal is to achieve a crumbly, slightly moist texture. The mixture should hold its shape when you press a handful together but should easily crumble when you apply slight pressure.
Adjusting: If the mixture is too dry, add a tablespoon of liquid at a time until you reach the desired consistency. If it's too wet, add a tablespoon of rice flour at a time. Remember, it's easier to add than to subtract, so go slowly.
Steaming: Layer the rice flour mixture with grated coconut in a Puttu maker and steam until cooked through. The Puttu is ready when steam escapes from the top.
Don't over-steam the Puttu! Over-steaming can make it dry and hard. Check for doneness by inserting a thin skewer into the Puttu; if it comes out clean, it's ready.
