Christmas Tree on Potato

While i was looking for ideas on what to make for the White Christmas Challenge, i came upon this Christmas Sushi. I thought it was pretty cute. I could have made a sushi since i have all the ingredients in my kitchen but i was just a little lazy to cook the sushi rice, well it's not difficult to cook sushi rice , it's just that i  didnt feel like doing that at that moment. So this idea is very much inspired by that Christmas Sushi. Actually i think making this is more like playing with food. I was just looking around in the kitchen and see what else can i used instead of making a sushi christmas tree. Ok , i see potatoes. Going to use that as a base for that christmas tree then. OK friends, my christmas tree may not look as pretty as the sushi christmas tree, or maybe you think it doesnt look like a christmas tree at all..hohoho! I roasted  some potatoes but now i think probably i need not roast the potatotes , maybe just boil it till just a little tender, i also think we need not flavour the potatoes because the tuna and avocado spread is quite a lot here, i dont think we would be able to taste the flavour of that little piece of potato here. The base of the christmas tree is potatoes, the tree itself is tuna with avocado spread, the fish eggs is for decoration and the mayonnaise is for ..errr..artificial snow.

Ingredients:
2 potatoes, peeled and each cut into halved
2 avocados
1 1/2 tsp of lemon juice
1 can of tuna ( i used ayam brand tuna chunks in water, drained )
some fish eggs and mayonnaise for decoration.

Here's what i did:
1. Boil the potatoes till their edge is a little soft ( takes around 10 minutes ), remove the water from the pan, place the lid back, shake the potatoes in the pot so that they turn floury. Remove and season them with salt and drizzle some olive oil onto your roasting pan and bake in a preheated oven at 190C for 30 minutes.  ( after eating this, i would think you can just boil the potatoes till cook is good enough , not necessary to roast them )
2. Meanwhile, you can make your spread. Mash the avocado , put in the lemon juice. In another bowl, mash the tuna till they become flakes, then add in the mashed avocado by spoonfuls till you get a spreadable or workable consistency. Mix them all together. Cut off a little top of the potatoes so that your spread can sit nicely on the potatoes. Using a gloves, take a small piece of that spread and shape into a cone shape and place that on top of that potato. Using a butter knife, slowly cover the base with more avocado spread and a little on the tree.
3.Sprinkle with fish eggs and pipe some mayonnaise around the tree.
