For a smooth Adai batter, grind the lentils to a consistency slightly coarser than semolina but finer than cracked wheat. The batter should be thick but pourable, without large, unground pieces.
Detailed Explanation:
Achieving the right texture for Adai batter is crucial for the final dish. The lentils and rice need to be ground to a specific consistency to ensure the Adai cooks evenly and has a pleasant mouthfeel. Here's a step-by-step guide to getting it right:
- Soaking: Soak the lentils (toor dal, chana dal, urad dal) and rice together for at least 4-6 hours, or preferably overnight. This softens the grains and makes grinding easier.
- Grinding: Use a high-powered blender or grinder. Add water gradually while grinding. The key is to add just enough water to create a smooth paste without making the batter too runny.
- Consistency Check: Aim for a texture that is slightly coarser than semolina (rava) but finer than cracked wheat (dalia). You should still feel a slight graininess, but there shouldn't be any large, unground pieces of lentils or rice.
- Fermentation (Optional): While not always necessary, allowing the batter to ferment for a few hours can enhance the flavor and texture of the Adai.
- Adjusting Consistency: If the batter is too thick, add a little water to reach a pourable consistency. If it's too thin, add a tablespoon or two of rice flour or besan (gram flour) to thicken it.
Pro Tip:
Soaking the lentils and rice in warm water can significantly reduce the grinding time and result in a smoother batter. Also, avoid over-grinding, as this can make the batter gummy.
