Whale milk tofu

Put the sake in a pot, put it on the fire and boil it down

Add the dried sardines to [1] and simmer until the flesh dissolves. This should take about 20 minutes

Remove the skin and strain until smooth

Use 150cc of [3]. Put it in a pot, add 150cc of milk, and heat over medium heat. Once it boils, add the remaining 100cc of milk and stir

Remove from heat and strain again, then transfer to a bowl and place over a pot of ice water to cool

Once cooled, pour into a deep tray lined with plastic wrap and place in the refrigerator to chill and harden for 20 to 30 minutes. If you're in a hurry, fill a tray with ice water and place it on top of that to chill

Once completely set, remove from the tray and cut into bite-sized pieces. Place in serving bowls and pour over the sauce made from [A]. Garnish with shredded shiso leaves and plum flesh to taste
