Whisk eggs, milk, 1/4 litre water and salt. Stir in the flour little by little. Cover the dough and let it swell for about 30 minutes. Heat some fat in a pan and bake 8 golden brown pancakes one after the other and keep them warm.
Coarsely chop the pistachios. Add honey and lime juice to the hot pan. Cut the bananas in half lengthwise and crosswise and heat in the honey. Spread the bananas on the pancakes. Sprinkle chopped pistachios over the pancakes and serve garnished with slices of lime and mint.
