Put 4 quail eggs in one plastic bag, and 4 in another. To one bag add some colorful brand furikake (spinach flavor), water and smoked salt & pepper mix. Add some Colorful brand furikake (tarako flavor) to the other bag with water and smoked salt & pepper mix. Let the eggs marinate overnight.
After marinating the quail eggs from 1/2 to 1 day, wipe them dry with a paper towel and skewer the eggs onto toothpicks, 3 colors per toothpick as shown here. The photo shows eggs that have been marinated for one full day.
This is the colorful rice seasoning that I used.
This is the hanami bento I made in 2012.
