In a large bowl mix together flour, baking powder, salt, sugar, nutmeg, and grated lime.
Then add the butter to the flour and mix well until the butter is well incorporated with the flour.
Whisk the egg into the mixture. Keep mixing until you have formed a sticky dough ball.
Dump the dough ball onto a floured surface and knead, incorporating more flour into the dough as needed, until the dough is smooth, elastic, and even in color and no longer sticky.
Divide the dough in half. On a floured board, roll each half about ⅙ inches thick. Just like linguine or fettuccine. You can make it easy by using a pasta machine if you have one available. Make shapes as desired.
