Slice half an onion and put it in a bowl with the sweet corn, the juice of three lemons, a pinch of salt. You can add a little bit of balsamic vinegar to add color to it. Leave it there, you will use it at the end.

Place the peeled potatoes in boiling water with salt until they are soft enough to be mashed

Mash the potatoes adding the olive oil, the pinch of curry and the aji paste

Prepare the tuna, add mayonnaise, the cilantro, a pinch of black pepper and salt

With a tall cookie cutter, or anything with a tall shape, even a can can be used as a mold place a layer of the mashed potatoes, like two fingers tall, then a layer of tuna, then a layer of sliced avocado, then finish a layer of mashed potatoes

Turn the mold on top of a plate and put on top of it two slices of hard boiled eggs and on top of that the mix of sliced onions and sweet corn. You can add basil or parsley to decorate it

* in the middle layer you can use chicken or shrimp instead.
