“Causa”: Wash the potatoes well and boil in abundant water and salt or cook in the oven. Once cooked, peel immediately and mash while hot to avoid lumps. Leave to cool and add the aji Amarillo paste, lime juice, salt and oil. Work with the hands to form a homogeneous dough. Keep cool in the refrigerator.
“Causa” rolls: Use a Japanese style bamboo grid covered in plastic wrap. Divide the dough in four equal parts and place one on the grid. Extend with the hands forming a square and fill with the avocado, the tomato and a little mayonnaise. Roll with the help of the grid until it is compact. Cut each roll in six equal parts.
Mount each roll with the cooked, peeled, and deveined shrimp, (chicken, tuna or vegetables) and cover with mayonnaise on top. Decorate with cilantro.
