Rinse chana dal in a bowl with several changes of cold water until water runs clear as it is poured off. Soak chana dal with enough cold water to cover by 1 inch for 1 1/2 hours.

Drain chana dal, then put in a food processor with 1/2 cup water and process to a grainy puree, stopping to scrape down sides and adding a little more water, if necessary, to help process. (Do not over grind and turn batter into a paste).

Cut out stem and center ribs from leaves to make 12 halves. If leaves from a package vary greatly in size, make 3 groups of 4 like-size halves (very large leaves, up to 20 inches, can be halved again crosswise so that one leaf is enough for all four layers) and divide chana dal stuffing into 3 amounts accordingly.

Working with one group at a time and roughly 1/3 of stuffing, turn leaves dull side up and spread a spoonful of filling over each, then stack leaves and roll up loosely from one narrow end to another. Place roll, seam side down, in basket of a steamer. Repeat procedure with remaining leaves and stuffing so that you have a total of three rolls (possibly of varying sizes) in steamer basket. Bring 1-inch of water to a boil in steamer, and steam rolls 15 minutes.

Transfer rolls to a cutting board and cut crosswise into scant 1/2-inch pinwheel slices. Arrange slices, a cut side up, on a serving platter.

Heat oil in a small skillet or very small saucepan over medium-high heat until almost smoking. Add mustard seeds, then cover skillet while seeds pop, about 1 minute. Uncover and add sesame seeds, then immediately pour oil with seeds over pinwheels. Squeeze lime juice over pinwheels then sprinkle with cilantro and coconut and serve.
