Wash off the pickling liquid from the octopuses and pat the octopuses dry. Spread the ponzu soy sauce, sugar, sesame oil and sesame seeds between two small bowls and stir until the sugar has dissolved. Divide the baby octopuses between the two bowls and mix with the marinade. Let the octopuses stand in the refrigerator for 15 minutes and stir again.
The octopuses fit as a side dish e.g., to miso soup with peas and sesame. Instructions can be found in my recipes.
My tip: use organic products and a measuring spoon set. I use xylitol instead of sugar.
