Standard way for kneading dough (for those who know how to knead) of these wonderful balls is the following: In the heated milk is added together with the yeast 1 tbsp sugar and flour in a large bowl. After the effervescent added to the mixture one after another, while beating with a mixer, the butter, olive oil, remaining sugar, eggs and pureed pineapple. Stir until complete dissolution of the sugar. Add 1/2 cup flour, beating until a homogeneous mixture, add salt and 1/2 cup again flour, again stirring until a homogeneous mixture. . and so add 1/2 cup he finished flour. You get slightly sticky dough, which leave to rise for about an hour and double in volume. Unconventional way for those who can not interfere (like me): In a shaker whisk the eggs, pineapple puree, sugar, olive oil, melted butter, milk and salt to a homogeneous mixture. As well dissolve the sugar is poured into bread machine, place the flour, yeast and 1 tbsp sugar (in this order) and turn the program dough. Once your dough rising, it split 12 balls (maybe more, depending on how you want to have your big the buns) and ranks in the pan. Leave them for 45 minutes to rise again. Before putting them to bake in the oven at 180 for about 25 minutes, coated them with broken egg yolk with milk and sunflower oil. Bake until browned. After removing them, no need to turn a towel because they are soft and fluffy even in the oven. Do not believe? Try and see for yourself! Enjoy your meal and Hawaiian!
