Yes, dosa batter can be fortified with oats and still ferment well, but the proportion of oats needs to be carefully controlled to avoid affecting the fermentation process and the final texture.
Adding oats to dosa batter can increase its nutritional value, particularly its fiber content. However, oats don't contain the same types of carbohydrates that are readily fermented by the bacteria and yeast responsible for the fermentation process in traditional dosa batter (which primarily relies on rice and lentils). Therefore, the key is to maintain a balance.
Here's a step-by-step guide to fortifying dosa batter with oats while ensuring proper fermentation:
To enhance fermentation when using oats, consider adding a small amount of fenugreek seeds (methi) to the batter. Fenugreek seeds are known to aid in fermentation and can also improve the flavor and texture of the dosa. Soak a teaspoon of fenugreek seeds along with the rice and lentils before grinding.
